TLV70233DBVR 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 pin, 2.0 V to 5.5 V. A small 1-µF ceramic capacitor from IN to GND is recommended for stability and good transient performance.
2	GND	power_in	Device ground reference. All voltages are referenced to this pin.
3	EN	input	Enable input. Driving EN above 0.9 V turns on the regulator; driving EN below 0.4 V puts the regulator into shutdown mode (~1 µA typical). Do not leave floating.
4	NC	unconnected	No internal connection. May be tied to GND to improve thermal dissipation.
5	OUT	power_out	Regulated 3.3-V output pin, capable of delivering up to 300 mA. Requires a small 1-µF ceramic capacitor from OUT to GND for stability.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlv70233dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`tlv70233dbvr-etched.step`	2.1 MB	You want the part with `TLV70233DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 516 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.
