A precision band-gap and error amplifier provides 2% accuracy over temperature. Quiescent current of only 1 µA makes these devices ideal solutions for battery-powered, always-on systems that require very little idle-state power dissipation. These devices have thermalshutdown, current-limit, and reverse-current protections for added safety. 1 • • • • • • • • • Qualified for Automotive Applications AEC-Q100 Qualified With the Following Results: – Device Temperature Grade 1: –40°C to 125°C Ambient Operating Temperature – Device HBM ESD Classification Level 2 – Device CDM ESD Classification Level C4B Input Voltage Range: 2.7 V to 30 V Ultralow IQ: 1 μA Reverse Current Protection Low ISHUTDOWN: 150 nA Supports 200-mA Peak Output 2% Accuracy Over Temperature Available in Fixed-Output Voltages: 1.2 V to 6.5 V Thermal Shutdown and Overcurrent Protection Packages: SOT-23-5, WSON-6 These regulators can be put into shutdown mode by pulling the EN pin low. The shutdown current in this mode goes down to 150 nA, typical. The TPS709-Q1 series is available in WSON-6 and SOT-23-5 packages.

The TPS709-Q1 offers reverse current protection to block any discharge current from the output into the input. The TPS709-Q1 also features current limit and thermal shutdown for reliable operation. 7.2 Functional Block Diagram OUT IN Current Limit Thermal Shutdown EN Bandgap Logic Device GND 7.3 Feature Description 7.3.1 Undervoltage Lockout (UVLO) The TPS709-Q1 uses an undervoltage lockout (UVLO) circuit to keep the output shut off until the internal circuitry operates properly. 7.3.2 Shutdown The enable pin (EN) is active high. Enable the device by forcing the EN pin to exceed VEN(HI) (0.9 V, minimum). Turn off the device by forcing the EN pin to drop below 0.4 V. 7.3.3 Reverse Current Protection The TPS709-Q1 has integrated reverse current protection. Reverse current protection prevents the flow of current from the OUT pin to the IN pin when output voltage is higher than input voltage. The reverse current protection circuitry places the power path in high impedance when the output voltage is higher than the input voltage. This setting reduces leakage current from the output to the input to 10 nA, typical. The reverse current protection is always active regardless of the enable pin logic state or if the OUT pin voltage is greater than 1.8 V. Reverse current can flow if the output voltage is less than 1.8 V and if input voltage is less than the output voltage. If voltage is applied to the input pin, then the maximum voltage that can be applied to the OUT pin is the lower of three times the nominal output voltage or 6.5 V. For example, if the 1.2-V output voltage version is used, then the maximum reverse bias voltage that can be applied to the OUT pin is 3.6 V. If the 3.3-V output voltage version is used, then the maximum reverse bias voltage that can be applied to the OUT pin is 6.5 V. 14 Submit Documentation Feedback Copyright © 2013–2018, Texas Instruments Incorporated Product Folder Links: TPS709-Q1 TPS709-Q1 www.ti.com SLVSCE6C – DECEMBER 2013 – REVISED JUNE 2018 Feature Description (continued) 7.3.4 Internal Current Limit The TPS709-Q1 internal current limit helps protect the regulator during fault conditions. During current limit, the output sources a fixed amount of current that is largely independent of output voltage. In such a case, the output voltage is not regulated, and can be measured as (VOUT = ILIMIT × RLOAD). The PMOS pass transistor dissipates [(VIN – VOUT) × ILIMIT] until a thermal shutdown is triggered and the device turns off. When cool, the device is turned on by the internal thermal shutdown circuit. If the fault condition continues, the device cycles between current limit and thermal shutdown; see the Thermal Information section for more details. The TPS709-Q1 is characterized over the recommended operating output current range up to 150 mA. The internal current limit begins to limit the output current at a minimum of 200 mA of output current. 7.3.5 Thermal Protection Thermal protection disables the output when the junction temperature rises to approximately 158°C, allowing the device to cool. When the junction temperature cools to approximately 140°C, the output circuitry is again enabled. Depending on power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit can cycle on and off. This cycling limits the dissipation of the regulator, protecting it from damage as a result of overheating. Any tendency to activate the thermal protection circuit indicates excessive power dissipation or an inadequate heatsink. For reliable operation, limit junction temperature to 125°C, maximum. To estimate the margin of safety in a complete design (including heatsink), increase the ambient temperature until the thermal protection is triggered; use worst-case loads and signal conditions. For good reliability, thermal protection must trigger at least 35°C above the maximum expected ambient condition of the particular application. This configuration produces a worst-case junction temperature of 125°C at the highest expected ambient temperature and worst-case load. The TPS709-Q1 internal protection circuitry is designed to protect against overload conditions. This circuitry is not intended to replace proper heatsinking. Continuously running the TPS709-Q1 into thermal shutdown degrades device reliability.

In this mode of operation, the output voltage is the same as the input voltage minus the dropout voltage. The transient performance of the device is significantly degraded because the pass device is in the linear region and no longer controls the current through the LDO. Line or load transients in dropout can result in large output voltage deviations. 7.4.3 Disabled The device is disabled under the following conditions: • The enable voltage is less than the enable falling threshold voltage or has not yet exceeded the enable rising threshold. • The device junction temperature is greater than the thermal shutdown temperature. Table 1 shows the conditions that lead to the different modes of operation. Table 1.

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 The TPS709-Q1 consumes low quiescent current and delivers excellent line and load transient performance. This performance, combined with low noise and good PSRR with little (VIN – VOUT) headroom, makes these devices ideal for RF portable applications, current limit, and thermal protection. The TPS709-Q1 devices are specified from –40°C to 125°C. 8.1.1 Input and Output Capacitor Considerations The TPS709-Q1 devices are stable with output capacitors with an effective capacitance of 2.0 μF or greater for output voltages below 1.5 V. For output voltages equal or greater than 1.5 V, the minimum effective capacitance for stability is 1.5 µF. The maximum capacitance for stability is 47 µF. The equivalent series resistance (ESR) of the output capacitor must be between 0 Ω and 0.2 Ω for stability. The effective capacitance is the minimum capacitance value of a capacitor after taking into account variations resulting from tolerances, temperature, and dc bias effects. X5R- and X7R-type ceramic capacitors are recommended because these capacitors have minimal variation in value and ESR over temperature. Although an input capacitor is not required for stability, good analog design practice is to connect a 0.1-µF to 2.2-µF capacitor from IN to GND. This capacitor counteracts reactive input sources and improves transient response, input ripple rejection, and PSRR. 8.1.2 Dropout Voltage The TPS709-Q1 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 approximately scales with the output current because the PMOS device functions like a resistor in dropout. The ground pin current of many linear voltage regulators increases substantially when the device is operated in dropout. This increase in ground pin current while operating in dropout can be several orders of magnitude larger than when the device is not in dropout. The TPS709-Q1 employs a special control loop that limits the increase in ground pin current while operating in dropout. This functionality allows for the most efficient operation while in dropout conditions that can greatly increase battery run times. 8.1.3 Transient Response As with any regulator, increasing the output capacitor size reduces over- and undershoot magnitude, but increases transient response duration.

The input voltage range must provide adequate headroom in order for the device to have a regulated output. This input supply must be wellregulated and stable. If the input supply is noisy, additional input capacitors with low ESR can help improve the output noise performance. 18 Submit Documentation Feedback Copyright © 2013–2018, Texas Instruments Incorporated Product Folder Links: TPS709-Q1 TPS709-Q1 www.ti.com SLVSCE6C – DECEMBER 2013 – REVISED JUNE 2018 10 Layout 10.1 Layout Guidelines 10.1.1 Board Layout Recommendations to Improve PSRR and Noise Performance Input and output capacitors must be placed as close to the device pins as possible. To improve ac performance (such as PSRR, output noise, and transient response), TI recommends that the board be designed with separate ground planes for VIN and VOUT, with the ground plane connected only at the device GND pin. In addition, the output capacitor ground connection must be connected directly to the device GND pin. High ESR capacitors may degrade PSRR performance. 10.1.2 Power Dissipation The ability to remove heat from the die is different for each package type, presenting different considerations in the printed circuit board (PCB) layout. The PCB area around the device that is free of other components moves the heat from the device to the ambient air. Performance data for JEDEC low- and high-K boards are given in the Thermal Information. Using heavier copper increases the effectiveness in removing heat from the device. The addition of plated through-holes to heat-dissipating layers also improves the heatsink effectiveness. Power dissipation depends on input voltage and load conditions. Power dissipation (PD) can be approximated by the product of the output current times the voltage drop across the output pass element (VIN to VOUT), as shown in Equation 1. PD = (VIN – VOUT) × IOUT (1) Figure 45 shows the maximum ambient temperature versus the power dissipation of the TPS709-Q1. This figure assumes the device is soldered on a JEDEC standard, high-K layout with no airflow over the board. Actual board thermal impedances vary widely. If the application requires high power dissipation, having a thorough understanding of the board temperature and thermal impedances is helpful to ensure the TPS709-Q1 does not operate above a junction temperature of 125°C.

These metrics are a more accurate representation of the heat transfer characteristics of the die and the package than RθJA. The junction temperature can be estimated with Equation 2. YJT: TJ = TT + YJT · PD YJB: TJ = TB + YJB · PD where: • • • PD is the power dissipation shown by Equation 1, TT is the temperature at the center-top of the IC package, TB is the PCB temperature measured 1 mm away from the IC package on the PCB surface. (2) NOTE Both TT and TB can be measured on actual application boards using a thermo-gun (an infrared thermometer).
