ICW1214A33M3GQ1 from ICW, in a SOT23-3. 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	VSS	power_in	Ground / return pin. Reference for VIN and VOUT. Connect to the system ground plane; place the 1 uF input capacitor close to VIN with a short return to this pin.
2	VOUT	power_out	Regulated output pin, factory-trimmed to 3.3 V ±2% for the '33' voltage code. Maximum output current 300 mA (typ.), dropout ~160 mV at IOUT = 100 mA. Requires a 1 uF ceramic output capacitor to VSS for stability.
3	VIN	power_in	Unregulated supply input, 2.0 V to 18 V operating range (absolute max 18 V). Bypass with a 1 uF ceramic capacitor to VSS placed close to the pin.
