ME6210A33PG from MICRONE, 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	VSS	power_in	Ground return for the regulator. Connect to system ground; the input and output capacitor return currents share this pin.
2	VIN	power_in	Unregulated power input, 2V to 18V (absolute max 18V). Decouple with a 10uF ceramic capacitor close to the pin. Note: SOT89-3 pin 2 is VIN, while on SOT23-3 pin 2 is VOUT.
3	VOUT	power_out	Regulated 3.3V output (±2% accuracy) supplying up to 500mA. Requires a 10uF ceramic output capacitor for stability. Dropout typ. 100mV at 100mA.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me6210a33pg.step`	57 KB	You want the bare part, or you mark your own boards.
`me6210a33pg-etched.step`	1.7 MB	You want the part with `ME6210A33PG` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 440 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.
