L78L08A from UMW, in a SO-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 8V output (7.7V min to 8.3V max at Tj=25°C) supplying up to 100mA, with a 0.1µF output capacitor recommended close to the regulator. |
| 2 | GND | power_in | Ground pin, tied to the other GND pins (2, 3, 6, 7) on the SOP-8 package. |
| 3 | GND | power_in | Ground pin, tied to the other GND pins (2, 3, 6, 7) on the SOP-8 package. |
| 4 | NC | unconnected | No internal connection. |
| 5 | NC | unconnected | No internal connection. |
| 6 | GND | power_in | Ground pin, tied to the other GND pins (2, 3, 6, 7) on the SOP-8 package. |
| 7 | GND | power_in | Ground pin, tied to the other GND pins (2, 3, 6, 7) on the SOP-8 package. |
| 8 | VIN | power_in | Unregulated input supply; the 78L08 is specified for VI from 10.5V to 23V, with a 0.33µF input capacitor recommended close to the regulator. |
