This device is available in a small, 6-pin, 2-mm × 2-mm WSON package and consumes very low quiescent current and provides fast line and load transient performance. The TLV759P features an ultra-low dropout of 225 mV at 1 A that can help improve the power efficiency of the system. 1 • • • • • • Input Voltage Range: 1.5 V to 6.0 V Adjustable Output Voltage: – 0.55 V to 5.5 V Very Low Dropout: – 225 mV (max) at 1 A (3.3 VOUT) High Output Accuracy: – 0.7%, Typical – 1%, Maximum Over Temperature (85°C) IQ: 25 µA (Typical) Built-In Soft-Start With Monotonic VOUT Rise Package: – 2-mm × 2-mm 6-Pin WSON (DRV) Active Output Discharge The TLV759P is optimized for a wide variety of applications by supporting an input voltage range from 1.5 V to 6.0 V and an externally adjustable output range of 0.55 V to 5.5 V. The low output voltage enables this LDO to power the modern microcontrollers with lower core voltages. Additionally, the TLV759P has a low IQ with enable functionality to minimize standby power. This device features an internal soft-start to lower the inrush current, which provides a controlled voltage to the load and minimizes the input voltage drop during start up. 2 Applications • • • • • • • Set-Top Boxes, Gaming Consoles Home Theater and Entertainment Desktops, Notebooks, Ultrabooks Printers Servers Thermostat and Lighting Controls Electronic Point of Sale (EPOS) The TLV759P is stable with small ceramic output capacitors, allowing for a small overall solution size. A precision band-gap and error amplifier provides a high accuracy of 0.7% max at 25ºC and 1% max over temperature (85ºC). This device includes integrated thermal shutdown, current limit, and undervoltage lockout (UVLO) features. The TLV759P has an internal foldback current limit that helps reduce the thermal dissipation during short-circuit events.

This device consumes low quiescent current and delivers excellent line and load transient performance. These characteristics, combined with low noise and good PSRR with low dropout voltage, make this device ideal for portable consumer applications. This regulator offers foldback current limit, shutdown, and thermal protection. The operating junction temperature for this device is –40°C to +125°C. 7.2 Functional Block Diagram OUT IN Current Limit – + Thermal Shutdown FB UVLO EN 95  Band Gap GND Logic 7.3 Feature Description 7.3.1 Undervoltage Lockout (UVLO) The TLV759P uses an undervoltage lockout (UVLO) circuit that disables the output until the input voltage is greater than the rising UVLO voltage (VUVLO). This circuit ensures that the device does not exhibit any unpredictable behavior when the supply voltage is lower than the operational range of the internal circuitry. When VIN is less than VUVLO, the output is connected to ground with a pulldown resistor (RPULLDOWN). 7.3.2 Shutdown The enable pin (EN) is active high. Enable the device by forcing the EN pin to exceed VEN(HI). Turn off the device by forcing the EN pin to drop below VEN(LO). If shutdown capability is not required, connect EN to IN. The TLV759P has an internal pulldown MOSFET that connects an RPULLDOWN resistor to ground when the device is disabled. The discharge time after disabling depends on the output capacitance (COUT) and the load resistance (RL) in parallel with the pulldown resistor (RPULLDOWN). Equation 1 calculates the time constant: τ = ( RPULLDOWN × RL) / (RPULLDOWN + RL) Copyright © 2018, Texas Instruments Incorporated (1) Submit Documentation Feedback 13 TLV759P SBVS352A – APRIL 2018 – REVISED DECEMBER 2018 www.ti.com Feature Description (continued) 7.3.3 Foldback Current Limit The device has an internal current limit circuit that protects the regulator during transient high-load current faults or shorting events. The current limit is a hybrid brickwall-foldback scheme. The current limit transitions from a brickwall scheme to a foldback scheme at the foldback voltage (VFOLDBACK). In a high-load current fault with the output voltage above VFOLDBACK, the brickwall scheme limits the output current to the current limit (ICL). When the voltage drops below VFOLDBACK, a foldback current limit activates that scales back the current as the output voltage approaches GND. When the output is shorted, the device supplies a typical current called the shortcircuit current limit (ISC). ICL and ISC are listed in the Electrical Characteristics table. For this device, VFOLDBACK = 0.4 V × VOUT(NOM). The output voltage is not regulated when the device is in current limit. When a current limit event occurs, the device begins to heat up because of the increase in power dissipation. When the device is in brickwall current limit, the pass transistor dissipates power [(VIN – VOUT) × ICL]. When the device output is shorted and the output is below VFOLDBACK, the pass transistor dissipates power [(VIN – VOUT) × ISC]. If thermal shutdown is triggered, the device turns off. After the device cools down, the internal thermal shutdown circuit turns the device back on. If the output current fault condition continues, the device cycles between current limit and thermal shutdown. For more information on current limits, see the Know Your Limits application report. Figure 39 shows a diagram of the foldback current limit. VOUT Brickwall VOUT(NOM) VFOLDBACK Foldback IOUT 0V 0 mA ISC IRATED ICL Figure 39. Foldback Current Limit 7.3.4 Thermal Shutdown Thermal shutdown protection disables the output when the junction temperature rises to approximately 170°C. Disabling the device eliminates the power dissipated by the device, allowing the device to cool. When the junction temperature cools to approximately 155°C, the output circuitry is again enabled. Depending on power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit may cycle on and off. This cycling limits regulator dissipation, protecting the LDO from damage as a result of overheating. Activating the thermal shutdown feature usually indicates excessive power dissipation as a result of the product of the (VIN – VOUT) voltage and the load current. For reliable operation, limit junction temperature to 125°C maximum. To estimate the margin of safety in a complete design, increase the ambient temperature until the thermal protection is triggered; use worst-case loads and signal conditions. 14 Submit Documentation Feedback Copyright © 2018, Texas Instruments Incorporated TLV759P www.ti.com SBVS352A – APRIL 2018 – REVISED DECEMBER 2018 Feature Description (continued) The TLV759P internal protection circuitry protects against overload conditions but is not intended to be activated in normal operation. Continuously running the TLV759P into thermal shutdown degrades device reliability. 7.4 Device Functional Modes 7.4.1 Device Functional Mode Comparison The Device Functional Mode Comparison table shows the conditions that lead to the different modes of operation. See the Electrical Characteristics table for parameter values. Table 1. Device Functional Mode Comparison PARAMETER OPERATING MODE VIN VEN IOUT TJ Normal operation VIN > VOUT(nom) + VDO and VIN > VIN(min) VEN > VEN(HI) IOUT < IOUT(max) TJ < TSD(shutdown) Dropout operation VIN(min) < VIN < VOUT(nom) + VDO VEN > VEN(HI) IOUT < IOUT(max) TJ < TSD(shutdown) VIN < VUVLO VEN < VEN(LOW) Not applicable TJ > TSD(shutdown) Disabled (any true condition disables the device) 7.4.2 Normal Operation The device regulates to the nominal output voltage when the following conditions are met: • The input voltage is greater than the nominal output voltage plus the dropout voltage (VOUT(nom) + VDO) • The output current is less than the current limit (IOUT < ICL) • The device junction temperature is less than the thermal shutdown temperature (TJ < TSD) • The enable voltage has previously exceeded the enable rising threshold voltage and has not yet decreased to less than the enable falling threshold 7.4.3 Dropout Operation If the input voltage is lower than the nominal output voltage plus the specified dropout voltage, but all other conditions are met for normal operation, the device operates in dropout mode. In this mode, the output voltage tracks the input voltage. During this mode, the transient performance of the device becomes significantly degraded because the pass transistor is in the ohmic or triode region, and acts as a switch. Line or load transients in dropout can result in large output-voltage deviations. When the device is in a steady dropout state (defined as when the device is in dropout, VIN < VOUT(NOM) + VDO, directly after being in a normal regulation state, but not during startup), the pass transistor is driven into the ohmic or triode region. When the input voltage returns to a value greater than or equal to the nominal output voltage plus the dropout voltage (VOUT(NOM) + VDO), the output voltage can overshoot for a short period of time while the device pulls the pass transistor back into the linear region. 7.4.4 Disabled The output of the device can be shutdown by forcing the voltage of the enable pin to less than the maximum EN pin low-level input voltage (see the Electrical Characteristics table). When disabled, the pass transistor is turned off, internal circuits are shutdown, and the output voltage is actively discharged to ground by an internal discharge circuit from the output to ground.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information 8.1.1 Adjustable Device Feedback Resistors Figure 40 shows that the output voltage of the TLV759P can be adjusted from 0.55 V to 5.5 V by using a resistor divider network. VIN IN CIN VOUT OUT R1 TLV759P GND COUT FB R2 VEN EN DNC Figure 40. Adjustable Operation The adjustable-version device requires external feedback divider resistors to set the output voltage. VOUT is set using the feedback divider resistors, R1 and R2, according to the following equation: VOUT = VFB × (1 + R1 / R2) (2) For this device, VFB = 0.55 V. To ignore the FB pin current error term in the VOUT equation, set the feedback divider current to 100x the FB pin current listed in the Electrical Characteristics table. This setting provides the maximum feedback divider series resistance, as shown in the following equation: R1 + R2 ≤ VOUT / (IFB × 100) (3) For this device, IFB = 10 nA. 8.1.2 Input and Output Capacitor Selection The TLV759P requires an output capacitance of 0.47 μF or larger for stability. Use X5R- and X7R-type ceramic capacitors because these capacitors have minimal variation in value and equivalent series resistance (ESR) over temperature. When choosing a capacitor for a specific application, pay attention to the dc bias characteristics for the capacitor. Higher output voltages cause a significant derating of the capacitor. For best performance, the maximum recommended output capacitance is 220 µF. Although an input capacitor is not required for stability, good analog design practice is to connect a capacitor from IN to GND. Some input supplies have a high impedance, thus placing the input capacitor on the input supply helps reduce the input impedance. This capacitor counteracts reactive input sources and improves transient response, input ripple, and PSRR. If the input supply has a high impedance over a large range of frequencies, several input capacitors can be used in parallel to lower the impedance over frequency. Use a higher-value capacitor if large, fast, rise-time load transients are anticipated, or if the device is located several inches from the input power source. 16 Submit Documentation Feedback Copyright © 2018, Texas Instruments Incorporated TLV759P www.ti.com SBVS352A – APRIL 2018 – REVISED DECEMBER 2018 Application Information (continued) 8.1.3 Dropout Voltage The TLV759P uses a PMOS pass transistor to achieve low dropout. When (VIN – VOUT) is less than the dropout voltage (VDO), the PMOS pass device is in the linear region of operation and the input-to-output resistance is the RDS(ON) of the PMOS pass element. VDO scales approximately with output current because the PMOS device behaves like a resistor in dropout mode. As with any linear regulator, PSRR and transient response degrade as (VIN – VOUT) approaches dropout operation. 8.1.4 Exiting Dropout Some applications have transients that place the LDO into dropout, such as slower ramps on VIN during start-up. As with other LDOs, the output may overshoot on recovery from these conditions. A ramping input supply causes an LDO to overshoot on start-up, as shown in Figure 41, when the slew rate and voltage levels are in the correct range. Use an enable signal to avoid this condition. Input Voltage Response time for LDO to get back into regulation. Load current discharges output voltage. VIN = VOUT(nom) + VDO Voltage Output Voltage Dropout VOUT = VIN - VDO Output Voltage in normal regulation. Time Figure 41. Startup Into Dropout Line transients out of dropout can also cause overshoot on the output of the regulator. These overshoots are caused by the error amplifier having to drive the gate capacitance of the pass element and bring the gate back to the correct voltage for proper regulation. Figure 42 illustrates what is happening internally with the gate voltage and how overshoot can be caused during operation. When the LDO is placed in dropout, the gate voltage (VGS) is pulled all the way down to ground to give the pass device the lowest on-resistance as possible. However, if a line transient occurs when the device is in dropout, the loop is not in regulation and can cause the output to overshoot until the loop responds and the output current pulls the output voltage back down into regulation. If these transients are not acceptable, then continue to add input capacitance in the system until the transient is slow enough to reduce the overshoot.

Line Transients From Dropout 8.1.5 Reverse Current As with most LDOs, excessive reverse current can damage this device. Reverse current flows through the body diode on the pass element instead of the normal conducting channel. At high magnitudes, this current flow degrades the long-term reliability of the device, as a result of one of the following conditions: • Degradation caused by electromigration • Excessive heat dissipation • Potential for a latch-up condition Conditions where reverse current can occur are outlined in this section, all of which can exceed the absolute maximum rating of VOUT > VIN + 0.3 V: • If the device has a large COUT and the input supply collapses with little or no load current • The output is biased when the input supply is not established • The output is biased above the input supply 18 Submit Documentation Feedback Copyright © 2018, Texas Instruments Incorporated TLV759P www.ti.com SBVS352A – APRIL 2018 – REVISED DECEMBER 2018 Application Information (continued) If reverse current flow is expected in the application, external protection must be used to protect the device. Figure 43 shows one approach of protecting the device. Schottky Diode IN CIN Internal Body Diode Device OUT COUT GND Figure 43. Example Circuit for Reverse Current Protection Using a Schottky Diode 8.1.6 Power Dissipation (PD) Circuit reliability requires consideration of the device power dissipation, location of the circuit on the printed circuit board (PCB), and correct sizing of the thermal plane. The PCB area around the regulator must have few or no other heat-generating devices that cause added thermal stress. To first-order approximation, power dissipation in the regulator depends on the input-to-output voltage difference and load conditions. Equation 4 calculates power dissipation (PD). PD = (VIN – VOUT) × IOUT (4) NOTE Power dissipation can be minimized, and therefore greater efficiency can be achieved, by correct selection of the system voltage rails. For the lowest power dissipation use the minimum input voltage required for correct output regulation. For devices with a thermal pad, the primary heat conduction path for the device package is through the thermal pad to the PCB. Solder the thermal pad to a copper pad area under the device. This pad area must contain an array of plated vias that conduct heat to additional copper planes for increased heat dissipation. The maximum power dissipation determines the maximum allowable ambient temperature (TA) for the device. According to Equation 5, power dissipation and junction temperature are most often related by the junction-toambient thermal resistance (RθJA) of the combined PCB and device package and the temperature of the ambient air (TA). TJ = TA + (RθJA × PD) (5) Thermal resistance (RθJA) is highly dependent on the heat-spreading capability built into the particular PCB design, and therefore varies according to the total copper area, copper weight, and location of the planes. The junction-to-ambient thermal resistance listed in the Thermal Information table is determined by the JEDEC standard PCB and copper-spreading area, and is used as a relative measure of package thermal performance. 8.2 Feed-Forward Capacitor (CFF) For the adjustable-voltage version device, a feed-forward capacitor (CFF) can be connected from the OUT pin to the FB pin. CFF improves transient, noise, and PSRR performance, but is not required for regulator stability. Recommended CFF values are listed in the Recommended Operating Conditions table. A higher capacitance CFF can be used; however, the startup time increases. For a detailed description of CFF tradeoffs, see the Pros and Cons of Using a Feedforward Capacitor with a Low-Dropout Regulator application report.
