TPMCP1700T-3302E from TECH PUBLIC, in a SOT-23L. 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	Ground return for the LDO. Connect directly to the system ground plane. Serves as the reference for the internal bandgap and error amplifier.
2	VOUT	power_out	Regulated output voltage (3.3 V for the -3302E option). Supplies up to 300 mA with ±2% accuracy. Requires a minimum 1 µF ceramic output capacitor to GND for stability.
3	VIN	power_in	Power input voltage, 1.2 V to 5.5 V operating range (absolute max 6.5 V). Bypass with a 1 µF ceramic capacitor to GND close to the pin. Must be at least VOUT + dropout (≈190 mV @ 250 mA for 2.8 V option) for regulation.
