ICW1235A50PGQ1 from ICW, in a SOT89-3. 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 5.0V output (ICW1235A50PGQ1) with ±2% accuracy and up to 200mA output current; the VOUT potential must not exceed VIN+0.3V. |
| 2 | GND | power_in | Ground pin. |
| 3 | VIN | power_in | Voltage input with an operating range of 2.2V to 40V (absolute maximum -0.3V to 45V); CIN of 1µF or more is required. |
