ICW1261A50P1GQ1

ICW · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3L

ICW1261A50P1GQ1 from ICW, in a SOT-89-3L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT power_out Regulated output voltage pin; the VOUT potential must not exceed VIN+0.3V to avoid reverse current through the parasitic diodes.
2 GND power_in Ground pin.
3 VIN power_in Power input pin; input voltage range is 2.2V to 60V in operation, with an absolute maximum of 65V (-0.3V to 65V).
