ME1502AM5G 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	VOUT	power_out	Switched power output pin, connects to USB VBUS. Sources current-limited 5V to the downstream load. Place output cap (10uF + 150uF typical) close to this pin.
2	GND	power_in	Device ground reference for internal circuitry and the RSET external resistor return.
3	RSET	input	Current-limit set pin. Connect an external resistor to GND to program the over-current threshold: Ioc = 60kΩ / Rset (e.g. Rset=30kΩ → Ioc≈2.0A). Place the resistor close to the pin to minimize parasitics.
4	EN	input	Chip enable input. For ME1502AM5G (A version) this pin is active-high (VIH ≥ 1.6V enables, VIL ≤ 0.4V shuts down). The C variant (ME1502CM5G) uses active-low polarity.
5	VIN	power_in	Power supply input, 2.7V to 5.5V (absolute max 6V). UVLO rising threshold ≈2.2V. Bypass with a ceramic cap (4.7uF typical) placed close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me1502am5g.step`	85 KB	You want the bare part, or you mark your own boards.
`me1502am5g-etched.step`	1.8 MB	You want the part with `ME1502AM5G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 450 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.
