TPRT9193-18GB 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 range up to 6V absolute maximum; typical application 1.6V-5.5V. Bypass with 1uF-10uF ceramic capacitor to GND.
2	GND	power_in	Device ground reference for the regulator and feedback network.
3	CE	input	Chip enable / shutdown control input (labeled EN in the block diagram, CE in the pin function table). Drive high to enable the regulator; drive low (Vce=0V) to place the device in shutdown mode (ICEL typ 1uA).
4	NC	unconnected	No internal connection. Leave floating or tie to GND on the PCB.
5	VOUT	power_out	Regulated voltage output. Fixed 1.8V nominal for the -18 option (VOUT tolerance ±2%). Delivers up to 300mA (typ), 450mA absolute max. Requires a 1uF-10uF ceramic output capacitor to GND for stability.
