TPS7A3301RGWR 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 power_out Regulator output. A capacitor ≥ 10 µF (47 µF ceramic recommended) must be tied from this pin to GND to assure stability, placed as close to the device as possible.
2 NC unconnected No connect. Can be left open or tied to any voltage between GND and IN.
3 FB input Feedback input to the control-loop error amplifier. Sets the output voltage; TI recommends a 10 nF capacitor from FB to OUT for AC performance.
4 NC unconnected No connect. Can be left open or tied to any voltage between GND and IN.
5 NC unconnected No connect. Can be left open or tied to any voltage between GND and IN.
6 NC unconnected No connect. Can be left open or tied to any voltage between GND and IN.
7 GND power_in Ground reference for the regulator. Also connected internally to the thermal pad.
8 NC unconnected No connect. Can be left open or tied to any voltage between GND and IN.
9 NC unconnected No connect. Can be left open or tied to any voltage between GND and IN.
10 NC unconnected No connect. Can be left open or tied to any voltage between GND and IN.
11 NC unconnected No connect. Can be left open or tied to any voltage between GND and IN.
12 NC unconnected No connect. Can be left open or tied to any voltage between GND and IN.
13 EN input Enable input. Regulator is enabled when VEN ≥ VEN(+HI) (typ. 2 V) or VEN ≤ VEN(-HI) (typ. VIN); disabled between VEN(+LO)/VEN(-LO). Can be tied to IN if not used.
14 NR/SS passive Noise-reduction / soft-start pin. A capacitor (1 µF recommended) from NR/SS to GND filters the internal bandgap reference noise and sets soft-start ramp.
15 IN power_in Negative input supply (-3 V to -35 V recommended). A capacitor ≥ 10 µF (10 nF ceramic close to the device also recommended) must be tied from IN to GND for stability and PSRR.
16 IN power_in Negative input supply (second IN pad). Tie to pin 15 and bypass to GND with ≥ 10 µF.
17 NC unconnected No connect. Can be left open or tied to any voltage between GND and IN.
18 NC unconnected No connect. Can be left open or tied to any voltage between GND and IN.
19 NC unconnected No connect. Can be left open or tied to any voltage between GND and IN.
20 OUT power_out Regulator output (second OUT pad). Tie to pin 1 and bypass to GND with a 47 µF ceramic capacitor.
PAD Thermal Pad power_in Exposed thermal pad on the bottom of the package. Internally connected to GND; solder to a large-area ground plane for thermal performance.
