L79L12ACD13TR from STMicroelectronics, in a SOIC-8. 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 | VOUT | power_out | Regulated negative output voltage of the L79L12AC regulator, nominal -12 V, delivering up to 100 mA. |
| 2 | VIN | power_in | Unregulated negative DC input voltage to the regulator; this pin is internally commoned to pins 3, 6, 7 and to the die-attach flag for improved thermal dissipation. |
| 3 | VIN | power_in | Unregulated negative DC input voltage to the regulator; this pin is internally commoned to pins 2, 6, 7 and to the die-attach flag for improved thermal dissipation. |
| 4 | NC | unconnected | Not internally connected. |
| 5 | GND | power_in | Ground/common reference pin for the regulator. |
| 6 | VIN | power_in | Unregulated negative DC input voltage to the regulator; this pin is internally commoned to pins 2, 3, 7 and to the die-attach flag for improved thermal dissipation. |
| 7 | VIN | power_in | Unregulated negative DC input voltage to the regulator; this pin is internally commoned to pins 2, 3, 6 and to the die-attach flag for improved thermal dissipation. |
| 8 | NC | unconnected | Not internally connected. |
