AP7361-15ER-13 from Diodes Incorporated, in a SOT-223R. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	GND	power_in	Ground pin, listed as Ground in the datasheet pin description table; the SOT223R marking diagram also gives pin 1 as GND.
2	OUT	power_out	The regulator output; bypass to ground through at least a 2.2µF ceramic capacitor, with a larger capacitor recommended for improved AC load response.
3	IN	power_in	The regulator input; bypass to ground through at least a 1µF ceramic capacitor. Input voltage range is 2.2V to 6.0V.
