HT7536S 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 / negative supply return. Common return for both input and output current.
2	VIN	power_in	Unregulated input supply. Absolute maximum 30V. A 10µF bulk/decoupling capacitor to GND is recommended (application circuit).
3	VOUT	power_out	Regulated output. 3.6V ±3% for HT7536, capable of ~60-100mA. A 10µF output capacitor to GND is recommended for stability.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ht7536s.step`	59 KB	You want the bare part, or you mark your own boards.
`ht7536s-etched.step`	1.4 MB	You want the part with `HT7536S` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 337 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.
