ME6214C45M5G 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 µF ceramic capacitor placed close to the pin.
2	VSS	power_in	Device ground / return pin (接地引脚). Reference for VIN, VOUT and CE voltages.
3	CE	input	Chip-enable input. VCEH ≥ 1.3 V turns the regulator ON, VCEL ≤ 0.7 V turns it OFF and engages the ~500 Ω output-capacitor discharge path. Must not be left floating (禁止悬空).
4	NC	unconnected	No internal connection (空). May be left floating or tied to VSS.
5	VOUT	power_out	Regulated 4.5 V output (±2 %). Sources up to 300 mA typical with 160 mV dropout at 100 mA. Requires a 1 µF ceramic output capacitor to VSS for stability.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me6214c45m5g.step`	85 KB	You want the bare part, or you mark your own boards.
`me6214c45m5g-etched.step`	2.1 MB	You want the part with `ME6214C45M5G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 525 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.
