TPAP7365-33WG from TECH PUBLIC, 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	VIN	power_in	Unregulated supply input. Operating range 1.2V to 5.5V (absolute max -0.3V to 6.5V vs GND). Bypass to GND with a 1µF-10µF ceramic capacitor placed close to the pin.
2	GND	power_in	Device ground reference for the internal reference, error amplifier, and output stage. Connect directly to the system ground plane.
3	EN	input	Enable input. Drive high (VIH ≥ 2V) to turn the regulator on; drive low (VIL ≤ 0.6V) to enter shutdown (typ. 10nA ISD). Absolute max -0.3V to 6V. Do not leave floating.
4	NC	unconnected	No internal connection. May be left floating or tied to GND for mechanical/thermal stability. In some derivatives of this family this position is a SNS (output sense) pin - see block diagram note.
5	VOUT	power_out	Regulated 3.3V fixed output (±2%), 600mA maximum load. Requires a 1µF-10µF ceramic or tantalum output capacitor to GND for stability. Absolute max -0.3V to 6V vs GND, and -6V to 0.3V relative to VIN.
