L7908CV-DG from STMicroelectronics, in a TO-220. 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 | OUT | power_out | Regulated negative output voltage (-8 V nominal for L7908C), rated for up to 1.5 A output current with internal thermal overload, short-circuit, and SOA protection. |
| 2 | IN | power_in | Unregulated negative DC input voltage; for L7908C the input operating range is -11.5 V to -23 V, with an absolute maximum input rating of -35 V. |
| 3 | GND | power_in | Common/ground reference terminal for the regulator, also connected to the metal tab for heatsinking. |
