ME2803A28M3G 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 voltage. Follows VIN when VIN is above the detect release voltage (+VDET); pulled to GND when VIN falls below the detect voltage (-VDET). Maximum output current 50mA (absolute max); typical Iout N-ch 0.14mA and P-ch 3.4mA at VDS=0.5V.
2	GND	power_in	Ground reference (0V). All internal reference and output stages are referenced to this pin.
3	VIN	power_in	Input supply and monitored voltage. Operating range 0.7V-7V (absolute max 8V). The internal comparator monitors this pin against the trimmed -VDET reference (2.8V for this variant).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me2803a28m3g.step`	59 KB	You want the bare part, or you mark your own boards.
`me2803a28m3g-etched.step`	2.6 MB	You want the part with `ME2803A28M3G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 606 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.
