DIO7002AST5 from DIOO, 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 power output pin. Decouple with a 10 µF ceramic capacitor to GND. Delivers up to 2.5 A of load current from the internal power FET (typ. 70 mΩ RDS(ON)).
2	GND	power_in	Ground reference for the device.
3	ISET	input	Current-limit programming pin. An external resistor RSET from ISET to GND sets the current limit per ILIM(A) = 6800 / RSET(Ω). Typical 6.8 kΩ → 1 A limit; do not program above 2.5 A.
4	EN	input	ON/OFF control input. For DIO7002AST5 (A variant) this pin is active-high: logic high enables the switch, logic low shuts it down. Compatible with TTL/CMOS logic (VEN(H) ≥ 2 V, VEN(L) ≤ 0.8 V). Do not leave floating.
5	IN	power_in	Input supply pin, 2.7 V to 5.5 V. Decouple with a 10 µF ceramic capacitor to GND to prevent input droop during hot-plug and improve short-circuit ruggedness.
