TPTLV73333PDBVR 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	Input supply voltage pin. Accepts 1.2V to 5.5V (absolute max -0.3V to 6.5V vs GND). A 1uF~10uF bypass capacitor to GND is recommended close to the pin.
2	GND	power_in	Ground reference for the regulator. All bypass and load return currents flow through this pin.
3	EN	input	Enable control input. Drive high (VENH typ 0.7V, min 0.5V) to enable the regulator; drive low (VENL typ 0.65V, max 0.85V) to enter shutdown (~0.1uA). Absolute max -0.3V to 6V vs GND; IEN < 0.1uA at VEN=5.5V. Must not be left floating.
4	NC	unconnected	No internal connection. Can be left floating or tied to GND for improved mechanical stability.
5	VOUT	power_out	Regulated output voltage pin (3.3V fixed for the '33' option). Supplies up to 300mA with 0.15V dropout at Vout>=3V. Requires a 1uF~10uF ceramic capacitor to GND for stability; active-discharge (~80 ohm) pulls this pin low when EN=0.
