L7905ACV 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 | OUTPUT | power_out | Regulated negative output voltage pin, capable of delivering output current up to 1.5 A with a heat sink. |
| 2 | INPUT | power_in | Unregulated DC input voltage pin; per Table 2, max input is -35 V for VO = -5 to -18 V variants (applies to the -5 V L7905AC). |
| 3 | GROUND | power_in | Common ground/reference pin for the regulator. |
