AP22811AW5-7 from Diodes Incorporated, in a SOT-25. 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	OUT	power_out	Switched voltage output pin. Connect a 0.1 µF bypass capacitor plus a high-value bulk capacitor (at least 10 µF for USB applications) to GND, close to the IC.
2	GND	power_in	Ground pin of the circuitry.
3	FLG	output	Open-drain fault report output. Asserts low when an over-current or over-temperature condition is detected (asserted/deasserted after the 6 ms typ. blanking time). Requires an external pull-up resistor (e.g. 10 kΩ). FLG FET on-resistance ~40 Ω.
4	EN	input	Enable input. AP22811A variant is active-high: drive above VIH (1.5 V min) to enable the switch, below VIL (0.5 V max) to disable. Do not float. Enable input leakage ≤1 µA.
5	IN	power_in	Input supply pin, 2.7 V to 5.5 V. Connect a 1 µF low-ESR bypass capacitor to GND close to the IC.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ap22811aw5-7.step`	85 KB	You want the bare part, or you mark your own boards.
`ap22811aw5-7-etched.step`	1.9 MB	You want the part with `AP22811AW5-7` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 486 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.
