AP2161WG-7 from Diodes Incorporated, 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	OUT	power_out	Switched voltage output pin. Delivers power to the load through the internal high-side power MOSFET (RDS(on) ≈ 95 mΩ typ). Recommended maximum continuous load current 1.0 A; internal current limit 1.5 A typ.
2	GND	power_in	Device ground reference.
3	FLG	output	Open-drain overcurrent / over-temperature fault report. Asserts active-low when a fault (over-current or thermal shutdown) is triggered, with a 7 ms typical blanking time. Requires an external pull-up resistor (e.g. 10 kΩ). FLG output FET on-resistance ≈ 20 Ω typ at IFLG = 10 mA.
4	EN	input	Enable input. Active-low on AP2161: drive low to turn the switch ON, high to turn OFF. VIL ≤ 0.8 V, VIH ≥ 2.0 V. EN input leakage ≤ 1 µA at VEN = 5 V.
5	IN	power_in	Input voltage pin. Operating range 2.7 V to 5.5 V; absolute maximum 6.5 V. Input UVLO ≈ 1.9 V typ. Input quiescent current 45 µA typ (enabled), shutdown current 0.5 µA typ.
