MC79L05ACDR from Texas Instruments, in a SOIC-8. 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 | OUTPUT | power_out | Regulated negative output voltage of the 3-terminal fixed negative regulator, rated for up to 100 mA output current. |
| 2 | INPUT | power_in | Negative unregulated input voltage; internally connected to pins 3, 6 and 7 (input voltage range per device variant, e.g. -7 V to -20 V for the 79L05). |
| 3 | INPUT | power_in | Negative unregulated input voltage; internally connected to pins 2, 6 and 7 (input voltage range per device variant, e.g. -7 V to -20 V for the 79L05). |
| 4 | NC | unconnected | No internal connection. |
| 5 | COMMON | power_in | Common (ground) reference terminal of the 3-terminal negative voltage regulator. |
| 6 | INPUT | power_in | Negative unregulated input voltage; internally connected to pins 2, 3 and 7 (input voltage range per device variant, e.g. -7 V to -20 V for the 79L05). |
| 7 | INPUT | power_in | Negative unregulated input voltage; internally connected to pins 2, 3 and 6 (input voltage range per device variant, e.g. -7 V to -20 V for the 79L05). |
| 8 | NC | unconnected | No internal connection. |
