TPRT9193-33GB 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	Supply power input. Operating input range 1.6V-5.5V (typical), absolute max 6V. Requires an input decoupling capacitor (1uF-10uF ceramic) to GND close to the pin.
2	GND	power_in	Device ground reference. Connect to system ground plane with a low-impedance path.
3	CE	input	Chip Enable / shutdown control input. Drive high to enable the regulator; drive low (Vce=0V) to place the device in shutdown mode where standby current ICEL is <1uA typical. Do not leave floating.
4	NC	unconnected	No internal connection. Leave floating or tie to GND for mechanical robustness.
5	VOUT	power_out	Regulated LDO output. Fixed 3.3V (-33GB option) with +/-2% accuracy, delivering up to 300mA (typ). Requires an output capacitor of 1uF-10uF ceramic for stability. Dropout ~90mV at 100mA and ~230mV at 200mA.
