TPS76933DBVR from Texas Instruments, in a SOT-23-5. 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	IN	power_in	Input supply voltage. Recommended operating range 2.7 V to 10 V (absolute max -0.3 V to 13.5 V). Bypass with a low-ESR ceramic capacitor to GND.
2	GND	power_in	Device ground reference. Carries only the ultralow ~17 µA quiescent current (28 µA max over temp).
3	EN	input	Active-low enable input. Drive low (VIL ≤ 0.9 V) to enable the regulator; drive high (VIH ≥ 1.7 V, up to VIN + 0.3 V) to place the device in shutdown (standby current ~1 µA typ). Input current ±1 µA max.
4	NC	unconnected	No internal connection on fixed-output versions (TPS76933 is a fixed 3.3-V option, so this pin is NC). On the adjustable TPS76901 this same pin is the FB feedback input.
5	OUT	power_out	Regulated 3.3-V output (3.201 V to 3.399 V over temperature at 10 µA-100 mA load). Requires a 4.7 µF (typ) low-ESR output capacitor for stability. Internally current-limited (350 mA typ, 750 mA max).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tps76933dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`tps76933dbvr-etched.step`	2.5 MB	You want the part with `TPS76933DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 587 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
