ME6203A33PG from MICRONE, in a SOT-89-3. 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	VSS	power_in	Ground reference pin. Connect to system ground and to the negative terminals of the input and output bypass capacitors.
2	VIN	power_in	Regulator input supply. Operating range 7V-30V (absolute max 36V). Bypass to VSS with a 10µF capacitor placed close to the pin.
3	VOUT	power_out	Regulated 3.3V output (±2.5% accuracy). Sources up to 100mA (VIN=7V) with internal short-circuit current limiting. Requires a 10µF output capacitor to VSS for stability.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me6203a33pg.step`	57 KB	You want the bare part, or you mark your own boards.
`me6203a33pg-etched.step`	1.8 MB	You want the part with `ME6203A33PG` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 468 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.
