ME2808A50M3G 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	Detector output. NMOS open-drain, active-low: normally high (via external pull-up) and pulled low when VIN drops below the 5.0 V detection threshold (VDET). Requires an external pull-up resistor to the desired logic rail. Output sink current typically 2.5 mA at VOUT=0.3 V for the 5.0 V variant.
2	GND	power_in	Ground / negative supply reference for the device. Common return for the input voltage divider, comparator, reference and output NMOS source.
3	VIN	power_in	Input supply and voltage being monitored. Absolute max 18 V; operating range 1.5 V to 18 V. Also acts as the sensed rail whose level is compared against the internal 5.0 V threshold.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me2808a50m3g.step`	59 KB	You want the bare part, or you mark your own boards.
`me2808a50m3g-etched.step`	2.5 MB	You want the part with `ME2808A50M3G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 602 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.
