XC6219B332MR-G from Torex Semicon, in a SOT-25. 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 input supply. Operating range 2.0 V to 6.0 V (absolute max 7 V). Bypass to VSS with a 1 µF ceramic capacitor (CIN) close to the pin.
2	VSS	power_in	Device ground reference. All voltages are referenced to VSS.
3	CE	input	Chip enable / ON-OFF control. Type B is active-high: VCE ≥ 1.6 V (max VIN) enables the regulator; VCE ≤ 0.25 V holds it in stand-by. Type B has no internal pull-down, so the pin must be driven - leaving it open results in an undefined state.
4	NC	unconnected	No internal connection. Leave floating or tie to VSS.
5	VOUT	power_out	Regulated LDO output, laser-trimmed to 3.3 V ±2%. Maximum output current 240 mA for VOUT ≥ 1.8 V (300 mA on E~H types). Requires a 1 µF ceramic output capacitor (CL) to VSS for stability; typical dropout 200 mV @ 100 mA.
