TPS70933QDBVRQ1 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	Unregulated input to the device. Operating range 2.7 V to 30 V (absolute max 32 V). Bypass with at least a 1-µF ceramic capacitor to GND close to the pin.
2	GND	power_in	Device ground reference. All voltages are referenced to this pin.
3	EN	input	Enable pin. Driving this pin high (VEN(HI) ≥ 0.9 V) enables the regulator; driving low (VEN(LO) ≤ 0.4 V) places the device into low-current shutdown (~150 nA). Can be left floating to enable the device. Maximum voltage must remain below 6.5 V.
4	NC	unconnected	No internal connection. Leave floating or tie to GND.
5	OUT	power_out	Regulated 3.3-V output, up to 150 mA. Connect a 2.2-µF (2 µF min, 47 µF max) or greater ceramic capacitor from this pin to ground to assure stability.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tps70933qdbvrq1.step`	85 KB	You want the bare part, or you mark your own boards.
`tps70933qdbvrq1-etched.step`	3.0 MB	You want the part with `TPS70933QDBVRQ1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 712 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.
