# ICW7805T2G

**ICW** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

ICW7805T2G from ICW, in a TO-252. 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 pin; for the ICW7805 the recommended VIN is 7 V to 25 V, with a 35 V absolute maximum input voltage. |
| 2 | COMMON | power_in | Common ground pin (地) shared by input and output; the datasheet gives no separate electrical limit for this pin. |
| 3 | OUTPUT | power_out | Regulated fixed output, 5.0 V nominal for the ICW7805 (4.75 V to 5.25 V over VIN 7 V to 18 V and IO 5 mA to 1000 mA), rated up to 1000 mA output current. |
