TPRT9013-33GB 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. Absolute max 7V; typically operated at VOUT+1V (e.g. ~4.3V for the -33GB 3.3V variant). Bypass with 1uF ceramic to GND.
2	GND	power_in	Device ground reference for the regulator, error amplifier, and reference. Connect to system ground plane.
3	CE	input	Chip Enable (active-high). VCE >= 1.1V enables the regulator; VCE = 0V places the part in shutdown with < 1uA standby current (ICEL). Do not leave floating.
4	NC	unconnected	No internal connection. May be left floating or tied to GND for board layout convenience.
5	VOUT	power_out	Regulated voltage output, fixed 3.3V (-33 suffix), ±2% accuracy. Delivers up to 500mA (typ). Requires a 1uF ceramic output capacitor to GND for stability.
