HT7530-1 from UMW, in a SOT-89. 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. Common return for the input and output. Connect to system ground.
2	VIN	power_in	Unregulated supply input. Absolute maximum 30V; a 10µF bypass capacitor to GND is recommended per the application circuit.
3	VOUT	power_out	Regulated output. Fixed 3.0V ±3% for the -30 variant, up to ~100mA output current with ~100mV dropout at 1mA. A 10µF output capacitor to GND is required for stability.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ht7530-1.step`	57 KB	You want the bare part, or you mark your own boards.
`ht7530-1-etched.step`	1013 KB	You want the part with `HT7530-1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 284 faces against 42 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.
