MC79L12ACDR from Texas Instruments, 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 | OUTPUT | power_out | Regulated negative output voltage pin; delivers up to 100 mA to the load with internal short-circuit and thermal-overload protection. |
| 2 | INPUT | power_in | Unregulated negative input voltage pin, internally connected to pins 3, 6 and 7; recommended range −14.5 V to −27 V for the MC79L12. |
| 3 | INPUT | power_in | Unregulated negative input voltage pin, internally connected to pins 2, 6 and 7; recommended range −14.5 V to −27 V for the MC79L12. |
| 4 | NC | unconnected | No internal connection; not connected inside the package. |
| 5 | COMMON | power_in | Common (ground) reference pin for the regulator. |
| 6 | INPUT | power_in | Unregulated negative input voltage pin, internally connected to pins 2, 3 and 7; recommended range −14.5 V to −27 V for the MC79L12. |
| 7 | INPUT | power_in | Unregulated negative input voltage pin, internally connected to pins 2, 3 and 6; recommended range −14.5 V to −27 V for the MC79L12. |
| 8 | NC | unconnected | No internal connection; not connected inside the package. |
