L78L15ACD13TR 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 output voltage pin (15 V nominal for L78L15), delivering up to 100 mA of output current. |
| 2 | GND | power_in | Ground pin; internally commoned to the die attach flag/heat-sink for improved thermal dissipation. |
| 3 | GND | power_in | Ground pin; internally commoned to the die attach flag/heat-sink for improved thermal dissipation. |
| 4 | NC | unconnected | Not internally connected pin. |
| 5 | NC | unconnected | Not internally connected pin. |
| 6 | GND | power_in | Ground pin; internally commoned to the die attach flag/heat-sink for improved thermal dissipation. |
| 7 | GND | power_in | Ground pin; internally commoned to the die attach flag/heat-sink for improved thermal dissipation. |
| 8 | VIN | power_in | Unregulated DC input voltage pin, rated up to 35 V for the 15 V output version (VO = 12 to 15 V). |
