TPMCP1702T-5002E from TECH PUBLIC, in a SOT-23-3L. 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	GND	power_in	Device ground reference. Connect to system ground with a low-impedance path; return path for the internal reference and pass-element bias currents.
2	VOUT	power_out	Regulated 5.0V output (5002 suffix). Delivers up to 300mA with typical dropout of 60mV at 40mA. Requires a ~10uF output capacitor to ground for stability, per the Typical Application Circuit.
3	VIN	power_in	Unregulated input supply. Recommended operating range VOUT+2 V to 22 V (absolute max -0.3 to +22 V). Bypass with ~10uF to GND at the pin.
