ICW7805T3G from ICW, in a TO-263. 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 | INPUT | power_in | Unregulated input supply; the datasheet gives a recommended VIN of 7 V to 25 V for the ICW7805, with an absolute maximum range of 7.0 V to 35 V. |
| 2 | COMMON | power_in | Common ground pin, shared between input and output as the return path for the regulator. |
| 3 | OUTPUT | power_out | Regulated 5 V output (VO 4.8 V to 5.2 V at TJ = 25 °C) that the datasheet rates for output currents up to 1000 mA. |
