AP7354D-33W5-7 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	VIN	power_in	Power input pin. Accepts 2.0V to 5.5V (absolute max 6.0V). Bypass with a 0.1µF ceramic capacitor to GND.
2	GND	power_in	Device ground reference. Chip ground return; all bypass capacitor grounds should tie here.
3	EN	input	Chip Enable. Drive high (≥1.0V, up to 5.5V/6.0V abs max) to enable the regulator; drive low (≤0.4V) to place the device in shutdown. Must not be left floating.
4	NC	unconnected	No internal connection. May be left floating or tied to GND.
5	VOUT	power_out	Regulated output. Fixed 3.3V for the -33 option, up to 150mA. Requires a 0.1µF output capacitor to GND. AP7354D variant includes an active output discharge resistor (~35Ω typ) engaged when EN is low.
