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 | VOUT | power_out | Regulated -8 V output. Delivers up to 100 mA. Recommended output decoupling capacitor 0.1 µF to GND. |+| 2 | VIN | power_in | Negative unregulated input voltage. Absolute maximum -30 V for -5 to -9 V variants (applies to L79L08AC). Recommended input decoupling capacitor 0.33 µF to GND. Pins 2, 3, 6 and 7 are electrically bonded to the die attach flag for improved thermal dissipation and must all be tied together to the input rail. |+| 3 | VIN | power_in | Negative unregulated input voltage. Internally commoned to pins 2, 6, 7 and the die attach flag for heat-sinking. Tie to the same input net as pin 2. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to GND per PCB convention. |+| 5 | GND | power_in | Ground / common return. Reference for both input and output voltages. |+| 6 | VIN | power_in | Negative unregulated input voltage. Internally commoned to pins 2, 3, 7 and the die attach flag for heat-sinking. Tie to the same input net as pin 2. |+| 7 | VIN | power_in | Negative unregulated input voltage. Internally commoned to pins 2, 3, 6 and the die attach flag for heat-sinking. Tie to the same input net as pin 2. |+| 8 | NC | unconnected | No internal connection.
