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. |
