HT7530S 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	Device ground / negative supply return. Tie to the system ground plane; the pin also carries the internal reference return.
2	VIN	power_in	Unregulated input supply. Absolute maximum 30 V; for the 7530 variant typical operating input is 5 V with 4 V ≤ VIN ≤ 30 V for line-regulation spec. Bypass with a 10 µF capacitor to GND close to the pin.
3	VOUT	power_out	Regulated 3.0 V ±3% output (2.91-3.09 V, VIN = 5 V, IOUT = 10 mA). Rated 60 mA min / 100 mA typ output current; requires a 10 µF output capacitor to GND for stability.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ht7530s.step`	59 KB	You want the bare part, or you mark your own boards.
`ht7530s-etched.step`	1.4 MB	You want the part with `HT7530S` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 338 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.
