LM7812T from HGSEMI, in a TO-220. 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 | VCC | power_in | Unregulated input supply pin; for the LM7812 the datasheet gives an input voltage range of 14.5 V to 35 V, with an absolute maximum input voltage of 35 V. |
| 2 | GND | power_in | Ground reference pin for the regulator, shared between input and output return. |
| 3 | OUT | power_out | Regulated 12 V output (datasheet typical 12 V, 11.5 V to 12.5 V at Io = 0.5 A), rated for a maximum output current of 1.2 A. |
