ME6216A33M3G 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 the system ground plane.
2	VOUT	power_out	Regulated 3.3V output (±1%). Rated for up to 300mA typical; place a 1µF ceramic output capacitor (COUT) to VSS close to the pin. Foldback current-limit / short-circuit protection is active on this pin.
3	VIN	power_in	Unregulated input supply, 1.0V to 6V (abs. max 6.5V). Must be at least VOUT + dropout (typ. 100mV @ 100mA, 210mV @ 200mA for 3.3V variant). Bypass with a 1µF ceramic input capacitor (CIN) to VSS.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me6216a33m3g.step`	59 KB	You want the bare part, or you mark your own boards.
`me6216a33m3g-etched.step`	2.4 MB	You want the part with `ME6216A33M3G` 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.
