L7912CV from STMicroelectronics, in a TO-220. 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 | GND | power_in | Ground reference pin of the regulator; the datasheet shows it as the bottom lead of the TO-220 top-view drawing. |
| 2 | IN | power_in | Negative unregulated input; absolute maximum DC input voltage is -35 V for VO = -5 to -18 V, and VI = -19 V is the L7912C test condition. |
| 3 | OUT | power_out | Regulated -12 V output (-11.5 to -12.5 V at TJ = 25 °C), output current internally limited with up to 1.5 A capability. |
