NCV78L08ABDR2G from onsemi, 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 8.0 V output delivering up to 100 mA; the output capacitor is optional and only improves transient response. |
| 2 | GND | power_in | Ground, electrically common to the die attach flag to lower thermal resistance. |
| 3 | GND | power_in | Ground, electrically common to the die attach flag to lower thermal resistance. |
| 4 | NC | unconnected | No internal connection. |
| 5 | NC | unconnected | No internal connection. |
| 6 | GND | power_in | Ground, electrically common to the die attach flag to lower thermal resistance. |
| 7 | GND | power_in | Ground, electrically common to the die attach flag to lower thermal resistance. |
| 8 | VIN | power_in | Input supply, which must stay typically 2.0 V above the output even at the low point of the input ripple, with an absolute maximum of 30 Vdc for 5.0-9.0 V versions. |
