TPS70933DBVR 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 input range 2.7 V to 30 V (absolute max 32 V). Bypass with 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. Drive high to enable the regulator; drive low to place the device in low-current shutdown (~150 nA typical). May be left floating to enable the device. Maximum voltage 6.5 V (absolute max 7 V).
4	NC	unconnected	No internal connection. May be left floating or tied to any potential.
5	OUT	power_out	Regulated 3.3-V output (fixed for TPS70933). Connect a 2.2-µF or larger ceramic capacitor from this pin to GND to ensure stability. Supplies up to 150 mA continuous (200-mA peak).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tps70933dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`tps70933dbvr-etched.step`	2.5 MB	You want the part with `TPS70933DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 588 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.
