HT7130S from UMW, in a SOT-23. 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	GND	power_in	Ground reference (0V). Common return for input and output; tie to system ground plane.
2	VIN	power_in	Unregulated input supply, 4V to 30V (absolute max 30V). Bypass with 10µF ceramic capacitor to GND close to the pin.
3	VOUT	power_out	Regulated 3.0V output (±3% tolerance, 2.91V-3.09V typ), up to 100mA. Requires 10µF output capacitor for stability. Dropout ~100mV at 1mA.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ht7130s.step`	59 KB	You want the bare part, or you mark your own boards.
`ht7130s-etched.step`	1.3 MB	You want the part with `HT7130S` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 316 faces against 69 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.
