TLV75733PDBVR from Texas Instruments, 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	IN	power_in	Unregulated input supply. Operating range 1.45 V to 5.5 V (absolute max 6 V). Requires a ceramic input capacitor ≥1 µF (effective ≥0.47 µF after derating) from IN to GND.
2	GND	power_in	Device ground return. Reference for VIN, VOUT and EN.
3	EN	input	Active-high enable input. Drive EN > VHI (1 V typ) to turn on the regulator; drive EN < VLO to place the LDO in shutdown (ISHDN ≈ 0.1 µA). Absolute max 6 V; recommended 0 V to 5.5 V. Do not float.
4	NC	unconnected	No internal connection. May be left floating or tied to GND for mechanical stability.
5	OUT	power_out	Regulated 3.3-V output (1% accuracy, 1 A max). Requires a ceramic output capacitor ≥1 µF (effective ≥0.47 µF after derating) from OUT to GND. Stable with 1 µF to 200 µF.
