ME2108C50M5G 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	CE	input	Chip enable input. Drive high to enable the converter; drive low to enter shut-down mode and reduce power dissipation. Absolute max range -0.3V to Vout+0.3V.
2	Vout	power_out	Regulated boost output and internal IC supply. Also serves as the output-voltage monitoring node fed back to the internal error amplifier and reference. Nominal 5.0V (this suffix), Vout0.975 to Vout1.025 tolerance (±2.5%).
3	NC	unconnected	No connect. Leave floating or tie to a static net; not internally bonded.
4	Vss	power_in	Device ground / negative supply return. Must have a solid low-impedance connection; per the application notes, poor Vss grounding shifts the internal zero reference with switching current and destabilizes the regulator.
5	Lx	output	Internal switching-transistor drain / boost switch node. Connects to the junction of the boost inductor and Schottky diode anode. Absolute max VLX=6.5V, ILX=600mA; typical switch current 360mA at VLX=0.4V.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me2108c50m5g.step`	85 KB	You want the bare part, or you mark your own boards.
`me2108c50m5g-etched.step`	2.4 MB	You want the part with `ME2108C50M5G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 586 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.
