The MC79L12ACDR is a three-terminal negative voltage regulator from the MC79L series, designed to provide a stable output voltage of -12V. It is typically available in a surface-mount package like the SOIC-8, which means it has 8 pins. However, not all pins are used for the regulation function, with the primary functional pins being:
1. Input (Vin): The pin where the input voltage is applied, which must be more negative than the -12V output.
2. Ground (GND): This pin serves as the reference point for the input and output voltages.
3. Output (Vout): The pin from which the regulated -12V output is drawn.
The remaining pins in the SOIC-8 package are generally not used for the core functionality of voltage regulation and may be internally connected or left unconnected. The MC79L12ACDR is designed for applications requiring a stable negative voltage, such as biasing circuits or powering negative-logic systems.
