H7325-A from Shanghai Siproin Microelectronics, 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 / common return for the regulator. Reference for both VIN and VOUT. Single-point ground tie recommended per the application circuit.
2	VOUT	power_out	Regulated +2.5V output (2.450V min / 2.500V typ / 2.550V max at IOUT=40mA). Delivers up to 250mA; requires a 10µF output capacitor (C2) to ground for stability per the basic application circuit.
3	VIN	power_in	Unregulated input supply. Operating range up to 15V (absolute maximum 18V); recommended VIN ≥ 3.5V for the 2.5V output. Requires a 10µF input capacitor (C1) to ground.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`h7325-a.step`	59 KB	You want the bare part, or you mark your own boards.
`h7325-a-etched.step`	1.1 MB	You want the part with `H7325-A` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 290 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.
