CJ6386A50MF from Changjing, in a SOT-23-5L. 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	Power input. Recommended supply range 2.5V to 45V (abs max 50V). Bypass with a 1µF ceramic capacitor to VSS close to the pin.
2	VSS	power_in	Ground reference for the regulator. All voltages are referenced to this pin.
3	NC	unconnected	No internal connection. May be left floating or tied to VSS for PCB routing convenience.
4	NC	unconnected	No internal connection. May be left floating or tied to VSS for PCB routing convenience.
5	VOUT	power_out	Regulated 5.0V output, up to 250mA. Requires a 1µF (ceramic or tantalum) output capacitor to VSS for stability.
