Pinout

The LM79L05ACM is a three-terminal negative voltage regulator with a fixed output of -5V. It typically comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. However, functionally, only three pins are actively used in the regulation process:
1. Input (Vin): This pin accepts the input voltage which should be higher in magnitude (more negative) than the regulated output voltage.
2. Ground (GND): This is the common ground pin for both the input and output voltage.
3. Output (Vout): This pin provides the regulated output voltage of -5V.
The remaining pins in the SOIC package are generally used for mechanical stability and are internally not connected to the functional components of the regulator. The LM79L05ACM is commonly used for providing a stable negative voltage output in various electronic circuits, ensuring reliable performance with low current applications.
