ME2807A45M3G 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	VOUT	output	CMOS output. Goes low when VIN falls below the detect threshold (4.5V for A45) and returns high on release above VDET(+). Output sink/source capability ~0.5mA typ; absolute range GND-0.3V to VIN+0.3V.
2	GND	power_in	Ground reference (0V).
3	VIN	power_in	Input supply and monitored voltage. Operating range 1.5V to 18V (absolute max 18V). Also the sensed voltage that the internal comparator compares against the reference to produce VOUT.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me2807a45m3g.step`	59 KB	You want the bare part, or you mark your own boards.
`me2807a45m3g-etched.step`	2.1 MB	You want the part with `ME2807A45M3G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 527 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.
