LM7812TG from HANSCHIP semiconductor, in a TO-220-3L. 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; the LM7812 electrical table gives VI of 14.5 V to 35 V, and the absolute maximum input voltage is 35 V. |
| 2 | GND | power_in | Common ground pin for the regulator, shared between input and output return. |
| 3 | OUT | power_out | Regulated 12 V output with Vo of 11.5 V to 12.5 V at VI=19 V and Io=0.5 A, and a maximum output current IOM of 1.2 A. |
