Pinout

The MC7805CTG is a three-terminal linear voltage regulator designed to provide a stable 5V output. It typically comes in a TO-220 package. The pin configuration and their functions are as follows:
1. Input (Pin 1): This pin receives the unregulated input voltage. The voltage supplied here should be higher than the desired output voltage (typically above 7V) to ensure proper regulation.
2. Ground (Pin 2): This pin is connected to the ground of both the input and output power supplies. It serves as a common reference point for input and output.
3. Output (Pin 3): This pin provides the regulated 5V output. It should be connected to the load circuit requiring the stable 5V supply.
The MC7805CTG typically requires external capacitors on both the input and output (commonly 0.33µF on the input and 0.1µF on the output) to improve stability and transient response. It features current limiting and thermal shutdown for protection.
