ME6214A33M3G from MICRONE, in a SOT-23-3. 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 (接地引脚). Connect to system ground; carries return current for both quiescent bias (~0.7 uA) and load current (up to 300 mA).
2	VOUT	power_out	Regulated voltage output (电压输出端). Fixed 3.3 V ±2% for the A33 option, delivers up to 300 mA with 160 mV typical dropout at 100 mA. Requires a 1 uF output capacitor (CL) to VSS for stability.
3	VIN	power_in	Unregulated supply input (电压输入端). Operating range 2.0 V to 18 V; absolute maximum 18 V. Requires a 1 uF input capacitor (CIN) to VSS for stability.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me6214a33m3g.step`	59 KB	You want the bare part, or you mark your own boards.
`me6214a33m3g-etched.step`	2.2 MB	You want the part with `ME6214A33M3G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 540 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.
