ME6214C33M5G from MICRONE, in a SOT-23-5. 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	VIN	power_in	Regulator input supply. Operating range 2.0 V to 18 V (absolute max 18 V). Bypass to VSS with a 1 uF ceramic capacitor close to the pin.
2	VSS	power_in	Ground / common return for the regulator (接地引脚).
3	CE	input	Chip enable input. Logic HIGH (VCEH >= 1.3 V) turns the regulator ON; logic LOW (VCEL <= 0.7 V) turns it OFF and enables the automatic load-capacitor discharge (~500 Ω). Must NOT be left floating (禁止悬空).
4	NC	unconnected	No internal connection (空). Leave floating or tie to VSS for mechanical stability.
5	VOUT	power_out	Regulated 3.3 V output. 300 mA rated output current; dropout typ 160 mV @ 100 mA. Requires a 1 uF ceramic load capacitor to VSS for stability.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me6214c33m5g.step`	85 KB	You want the bare part, or you mark your own boards.
`me6214c33m5g-etched.step`	2.3 MB	You want the part with `ME6214C33M5G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 568 faces against 102 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.
