ME6209A50M3G from MICRONE, in a SOT-23-3L. 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 for the regulator. Connect to system ground with a low-impedance return.
2	VOUT	power_out	Regulated 5.0V output. Requires a 10µF ceramic output capacitor for stability. Supplies up to 250mA within the package power dissipation limit (SOT-23-3: 300mW).
3	VIN	power_in	Unregulated input supply, 5.0V to 18V absolute max. Requires a 10µF ceramic input capacitor; a small (~1Ω) series resistor is recommended if driving from an AC/DC supply with ceramic bypass to suppress voltage spikes.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me6209a50m3g.step`	59 KB	You want the bare part, or you mark your own boards.
`me6209a50m3g-etched.step`	2.4 MB	You want the part with `ME6209A50M3G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 572 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.
