These devices consume low quiescent current and deliver excellent line and load transient performance. These characteristics, combined with low noise, very good PSRR with little (VIN – VOUT) headroom, make this family of devices ideal for RF portable applications. This family of regulators offers current foldback. Device operating junction temperature is –40°C to 85°C. 7.2 Functional Block Diagram IN OUT Foldback Current Limit UVLO EN 120 W Bandgap LOGIC GND Copyright © 2016, Texas Instruments Incorporated 7.3 Feature Description 7.3.1 Internal Current Limit The TLV717P has an internal foldback current limit that helps to protect the regulator during fault conditions. The current supplied by the device is gradually throttled down as the output voltage decreases. When the output is shorted, the LDO supplies a typical current of 40 mA. Output voltage is not regulated when the device is in current limit, and is VOUT = ILIMIT × RLOAD. The advantage of foldback current limit is that the ILIMIT value is less than the fixed current limit. Therefore, the power that the PMOS pass transistor dissipates [(VIN – VOUT) × ILIMIT] is much less. The TLV717P PMOS pass element has a built-in body diode that conducts current when the voltage at OUT exceeds the voltage at IN. This current is not limited, so if extended reverse voltage operation is anticipated, external limiting to 5% of the rated output current is recommended.

The device is enabled when the voltage at the EN pin goes above 0.9 V. This relatively lower voltage value required to turn the LDO on can be exploited to power the LDO with a GPIO of recent processors whose GPIO logic 1 voltage level is lower than traditional microcontrollers. The device is turned off when the EN pin is held at less than 0.4 V. When shutdown capability is not required, EN can be connected to the IN pin. 7.3.3 Undervoltage Lockout (UVLO) The TLV717P uses an undervoltage lockout circuit (UVLO = 1.6 V) to keep the output shut off until the internal circuitry operates properly. 7.4 Device Functional Modes 7.4.1 Normal Operation The device regulates to the nominal output voltage under the following conditions: • • • • The input voltage has previously exceeded the UVLO rising voltage and has not decreased below the UVLO falling threshold. The input voltage is greater than the nominal output voltage added to the dropout voltage. The enable voltage has previously exceeded the enable rising threshold voltage and not decreased below the enable falling threshold. The output current is less than the current limit. 7.4.2 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 condition, the output voltage is the same the input voltage minus the dropout voltage. The transient performance of the device is significantly degraded because the pass device is in a triode state and no longer controls the current through the LDO. Line or load transients in dropout may result in large output voltage deviations. 7.4.3 Disabled The device is disabled under the following conditions: • The input voltage is less than the UVLO falling voltage, or has not yet exceeded the UVLO rising threshold. • The enable voltage is less than the enable falling threshold voltage or has not yet exceeded the enable rising threshold. When the device is disabled, the active pulldown resistor discharges the output. Table 1 lists 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 TLV717P is a low-dropout regulator (LDO) with low quiescent current that delivers excellent line and load transient performance. This LDO regulator offers a foldback current limit. The operating junction temperature of this device series is –40°C to 85°C. 8.2 Typical Application VIN OUT IN CIN COUT VOUT 1 mF Ceramic TLV717xx Series On Off EN GND Copyright © 2016, Texas Instruments Incorporated Figure 15. Typical Application Circuit 8.2.1 Design Requirements Table 2 lists the parameters for this application. Table 2. Design Parameters PARAMETER DESIGN REQUIREMENT Input voltage 3.8 V Output voltage 2.8 V ±1% Output current 30 to 150 mA 8.2.2 Detailed Design Procedure 8.2.2.1 Input and Output Capacitor Requirements TI recommends X5R- and X7R-type ceramic capacitors because they have minimal variation in value and equivalent series resistance (ESR) over temperature. The TLV717P is designed to be stable with an effective capacitance of 0.1 µF or larger at the output, though TI recommends a 1-µF ceramic capacitor for typical applications. Thus, the device is stable with capacitors of other dielectric types as well, as long as the effective capacitance under operating bias voltage and temperature is greater than 0.1 µF. This effective capacitance refers to the capacitance that the LDO detects under operating bias voltage and temperature conditions; that is, the capacitance after taking both bias voltage and temperature derating into consideration. In addition to allowing the use of cheaper dielectrics, this capability of being stable with 0.1-µF effective capacitance also enables the use of smaller footprint capacitors that have higher derating in size- and space-constrained applications. Using a 0.1-µF rated capacitor at the LDO output does not ensure stability because the effective capacitance under the specified operating conditions would be less than 0.1 µF. Maximum ESR should be less than 200 mΩ. Although an input capacitor is not required for stability, it is good analog design practice to connect a 0.1-µF to 1µF, low ESR capacitor across the IN and GND pins of the regulator. This capacitor counteracts reactive input sources and improves transient response, noise rejection, and ripple rejection. A higher-value capacitor may be necessary if large, fast, rise-time load transients are anticipated, or if the device is not located close to the power source. If source impedance is more than 2 Ω, a 0.1-µF input capacitor may be necessary to ensure stability.

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. As with any linear regulator, PSRR and transient response are degraded as (VIN – VOUT) approaches dropout. 8.2.2.3 Transient Response As with any regulator, increasing the size of the output capacitor reduces over- and undershoot magnitude but increases the duration of the transient response. 8.2.3 Application Curves 10 Noise Spectral Density (mV/ÖHz) Ground Pin Current (mA) 3000 2500 2000 1500 1000 +85°C +25°C -40°C 500 0.1 0.01 1.2 2.8 5 0 0 0 25 50 75 100 Output Current (mA) 125 150 10 100 1k 10k 100k Frequency (Hz) G008 Figure 16.

Inductive impedances between the input supply and the IN pin can create significant voltage excursions at the IN pin during start-up or load transient events. If inductive impedances are unavoidable, use an input capacitor. 10 Layout 10.1 Layout Guidelines Input and output capacitors should be placed as close to the device pins as possible. To improve AC performance (such as PSRR, output noise, and transient response), TI recommends designing the board 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 should be connected directly to the device GND pin. High ESR capacitors may degrade PSRR performance. 10.2 Layout Example VOUT VIN 1 4 COUT CIN 2 3 GND PLANE Represents via used for application specific connections Copyright © 2016, Texas Instruments Incorporated Figure 18. Recommended Layout Example 10.3 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 ambient air. Performance data for JEDEC-low and high-K boards are given in Thermal Information. Using heavier copper increases the effectiveness in removing heat from the device. The addition, plated through-holes to heat-dissipating layers also improves heatsink effectiveness. Power dissipation depends on input voltage and load conditions. Power dissipation (PD) is equal to the product of the output current and the voltage drop across the output pass element, as shown in Equation 1.
