TPS7A4700RGWR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · VQFN-20-EP(5x5)

TPS7A4700RGWR from Texas Instruments, in a VQFN-20-EP(5x5). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT output Regulator output requiring ≥10µF capacitor to ground for stability and recommended 47µF ceramic capacitor for optimal AC performance.
2 NC unconnected No connect pin that may remain floating or connected to any voltage between GND and IN.
3 SENSE input SENSE pin for control loop that must be connected to OUT, preferably at load point for maximum accuracy.
4 6P4V2 input Adds 6.4V to 1.4V reference voltage when connected to GND; do not connect other voltages and leave open if unused.
5 6P4V1 input Adds 6.4V to 1.4V reference voltage when connected to GND; do not connect other voltages and leave open if unused.
6 3P2V input Adds 3.2V to 1.4V reference voltage when connected to GND; do not connect other voltages and leave open if unused.
7 GND power_in Ground connection providing reference for all signal and power pins.
8 1P6V input Adds 1.6V to 1.4V reference voltage when connected to GND; do not connect other voltages and leave open if unused.
9 0P8V input Adds 0.8V to 1.4V reference voltage when connected to GND; do not connect other voltages and leave open if unused.
10 0P4V input Adds 0.4V to 1.4V reference voltage when connected to GND; do not connect other voltages and leave open if unused.
11 0P2V input Adds 0.2V to 1.4V reference voltage when connected to GND; do not connect other voltages and leave open if unused.
12 0P1V input Adds 0.1V to 1.4V reference voltage when connected to GND; do not connect other voltages and leave open if unused.
13 EN input Enable pin that enables device when voltage exceeds V+EN(HI) threshold of 2.0V; connect to IN if always enabled is required.
14 NR input Noise reduction pin requiring ≥10nF capacitor to ground for stability and recommended 1µF for optimal AC performance and minimal noise.
15 IN power_in Input power supply pin requiring ≥1µF capacitor to ground for stability and recommended 10µF close to device for reduced PCB layout sensitivity.
16 IN power_in Input power supply pin requiring ≥1µF capacitor to ground for stability and recommended 10µF close to device for reduced PCB layout sensitivity.
17 NC unconnected No connect pin that may remain floating or connected to any voltage between GND and IN.
18 NC unconnected No connect pin that may remain floating or connected to any voltage between GND and IN.
19 NC unconnected No connect pin that may remain floating or connected to any voltage between GND and IN.
20 OUT output Regulator output requiring ≥10µF capacitor to ground for stability and recommended 47µF ceramic capacitor for optimal AC performance.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
