LM79L05ACMX from Texas Instruments, in a SOIC-8-150mil. 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 | -VOUT | power_out | Negative regulated output voltage pin. Provides -5V nominal at up to 100mA (LM79L05AC variant). Requires a 0.1µF output capacitor for stability. |
| 2 | -VIN | power_in | Negative unregulated input voltage pin. Absolute maximum -35V; typical operating range -7.3V to -20V for the -5V variant. Tied together with pins 3 and 7 (all -VIN). |
| 3 | -VIN | power_in | Negative unregulated input voltage pin. Internally connected to pins 2 and 7. Multiple input pins improve thermal dissipation in the SOIC package. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to GND per PCB convenience. |
| 5 | GND | power_in | Ground / common return pin for the regulator. Reference for both input and output voltages. |
| 6 | -VIN | power_in | Negative unregulated input voltage pin. Internally connected to the other -VIN pins. |
| 7 | -VIN | power_in | Negative unregulated input voltage pin. Internally connected to pins 2, 3, and 6. |
| 8 | NC | unconnected | No internal connection. Leave floating or tie to GND per PCB convenience. |
