CJ6206B25M 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 power input. Operating range 2.0V to 7.0V (absolute max VSS+8V). Bypass to VSS with a 1µF low-ESR ceramic capacitor placed close to the pin.
2	VSS	power_in	Device ground reference (negative supply return). Common return for input and output capacitors.
3	CE	input	Chip Enable / shutdown control, TTL-logic input. VCE ≥ 1.5V enables the regulator (max = VIN); VCE ≤ 0.3V puts the part into shutdown (ISTBY ≤ 0.1µA). Do not leave floating.
4	NC	unconnected	No internal connection. May be left floating or tied to VSS for mechanical robustness.
5	VOUT	power_out	Regulated 2.5V output (±2% typ.), up to 300mA. Requires a 1µF low-ESR ceramic output capacitor to ground for stability. Built-in current-limit and short-circuit protection (IShort ≈ 50mA when VOUT is shorted to VSS).
