78M12-MS from MSKSEMI, in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Unregulated positive input supply. Accepts up to 35V absolute maximum; recommended operating range approximately 14.5V to 30V for a 12V output. Bypass to GND with a 0.33μF capacitor close to the pin. |
| 2 | GND | power_in | Common ground reference for input and output. Internally connected to the tab/heat slug of the TO-252 package, providing the primary thermal path to the PCB. |
| 3 | OUT | power_out | Regulated +12V output. Nominal 12V ±0.5V at Io=5-350mA, up to 500mA maximum (IOM 0.5A). Bypass to GND with a 0.1μF capacitor close to the pin for stability. |
