The MC79L05ACDR is a three-terminal negative voltage regulator with a fixed output voltage of -5V. It typically comes in a surface-mount package such as the SOIC-8 (Small Outline Integrated Circuit), which has 8 pins. However, only three of these pins are functionally significant for its operation as a voltage regulator:
1. Input (Pin 1): This is the pin where the unregulated negative input voltage is applied. The input voltage must be more negative than the output voltage by a certain margin to ensure proper regulation.
2. Ground/Common (Pin 2): This pin is connected to the ground or common reference point in the circuit.
3. Output (Pin 3): This pin provides the regulated -5V output.
The other pins in the SOIC-8 package may not be connected (NC) or used for additional features like thermal and electrical connectivity, but they do not serve a primary function in voltage regulation. Always refer to the manufacturer’s datasheet for detailed pin configuration and application guidance.
