HX7812CTG from HANSCHIP semiconductor, in a TO-220-3. 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 | VCC | power_in | Unregulated input supply; for the HX7812C the input voltage VI is specified at 14.5 V to 35 V, and the absolute maximum input voltage is 35 V. |
| 2 | GND | power_in | Ground reference pin for the regulator (datasheet function: 地, ground). |
| 3 | OUT | power_out | Regulated 12 V output (Vo typ. 12 V at Io=0.5 A) with maximum output current IOM of 1.5 A. |
