L78L05CD13TR 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; delivers up to 100 mA of output current with internal current limiting and thermal shutdown protection. |
| 2 | GND | power_in | Ground reference pin, internally connected to the die-attach flag (pins 2, 3, 6 and 7 are electrically commoned) to improve heat dissipation. |
| 3 | GND | power_in | Ground reference pin, internally connected to the die-attach flag (pins 2, 3, 6 and 7 are electrically commoned) to improve heat dissipation. |
| 4 | NC | unconnected | Not internally connected pin. |
| 5 | NC | unconnected | Not internally connected pin. |
| 6 | GND | power_in | Ground reference pin, internally connected to the die-attach flag (pins 2, 3, 6 and 7 are electrically commoned) to improve heat dissipation. |
| 7 | GND | power_in | Ground reference pin, internally connected to the die-attach flag (pins 2, 3, 6 and 7 are electrically commoned) to improve heat dissipation. |
| 8 | VIN | power_in | DC input voltage pin; for the 5 V output grade the input voltage must not exceed 30 V absolute maximum, with a recommended dropout of 2 V above the regulated output. |
