LT6650CS5#TRMPBF from Analog Devices, in a TSOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	FB	input	Resistor divider feedback pin; connect a divider from OUT to GND with the center tap to FB to set the output potential.
2	GND	power_in	Ground connection.
3	DNC	unconnected	Do not connect; connected internally for post package trim and must be left unconnected.
4	IN	power_in	Positive supply, 1.4V to 18V operating range; bypassing with a 1µF capacitor is recommended if the output loading changes.
5	OUT	output	Reference output that sources and sinks current; stable with total load capacitance of 1µF or more.
