Pinout
The pin functions are as follows:
1. Input (Pin 1): This pin is connected to the higher voltage input supply that needs to be regulated. The input voltage should be higher than the desired output voltage (12V in this case) and should be within the specified input voltage range of the regulator.
2. Ground (Pin 2): This is the common ground pin and is connected to the ground of both the input and the load circuitry.
3. Output (Pin 3): This pin provides the regulated 12V output. It is connected to the load that requires the stabilized voltage supply.
The MC7812BTG is used in various applications where a reliable 12V DC supply is needed.
