ME6209A25M3G from MICRONE, 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	VSS	power_in	Ground / negative supply reference for the regulator. Connect to system ground with a low-impedance return, close to the input and output decoupling capacitors.
2	VOUT	power_out	Regulated 2.5V output (±2%). Delivers up to 250mA (typical Iout_max) with 100mV typ. dropout at 40mA. Requires a 10µF ceramic output capacitor (COUT) to ground for stability.
3	VIN	power_in	Unregulated positive supply input, up to 18V absolute maximum. Bypass to VSS with a 10µF ceramic capacitor (CIN) placed close to the pin.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me6209a25m3g.step`	59 KB	You want the bare part, or you mark your own boards.
`me6209a25m3g-etched.step`	2.4 MB	You want the part with `ME6209A25M3G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 562 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.
