Pinout
The MC7812BDTG is a three-terminal positive voltage regulator. It typically comes in a TO-220 package with three pins. Here are the functions of each pin:
1. Input (Pin 1): This is the pin where the unregulated input voltage is applied. The input voltage must be higher than the desired output voltage, usually by a few volts, to ensure proper regulation.
2. Ground (Pin 2): This pin is connected to the ground (0V reference) of both the input and output circuits. It acts as a common reference point for the input and output voltages.
3. Output (Pin 3): This pin provides a regulated output voltage. For the MC7812BDTG, the output is a stable 12V, suitable for powering devices that require this voltage level.
The MC7812BDTG is designed to provide a fixed output of 12V, with a maximum output current of 1.5A. It's commonly used in electronic circuits to provide a stable voltage from a higher voltage source, offering features like thermal shutdown, current limiting, and safe area protection.
