CJ6205B25M 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	Unregulated positive power input. Operating range 2.0 V to 6.0 V; absolute max VSS-0.3 V to VSS+7 V. Bypass to VSS with 1 uF ceramic close to the pin.
2	VSS	power_in	Device ground / negative supply return. Common reference for VIN, VOUT and CE.
3	CE	input	TTL chip-enable input. High enables the regulator (VCE-H min 1.5 V, up to VIN); Low shuts it down (VCE-L max 0.3 V, ISTBY <=0.1 uA). On the 'B' variant an internal pull-down holds the part off if CE is left floating and a COUT discharge resistor pulls VOUT down when disabled.
4	NC	unconnected	No internal connection. Leave floating or tie to VSS.
5	VOUT	power_out	Regulated 2.5 V output (accuracy typ. +/-2%, VOUT0.98 to VOUT1.02). 500 mA typ output current, 100 mA short-circuit current limit. Requires 1 uF ceramic load cap; typical dropout 150 mV @150 mA.
