ICW1232C33M5GQ1

ICW · Linear Voltage Regulators (LDO) · SOT-23-5

ICW1232C33M5GQ1 from ICW, in a SOT-23-5. 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 VIN power_in Voltage input with an operating range of 1.8V to 5.5V (absolute maximum 6.5V).
2 VSS power_in Ground pin.
3 CE input Enable input; high level of at least 1.2V turns the output on, low level of at most 0.4V shuts it down with 0uA typical shutdown current.
4 NC unconnected No-connect pin, not internally used.
5 VOUT power_out Regulated 3.3V output (±1% accuracy) with up to 400mA maximum output current.
