MC78T12 12V 3A Voltage Regulator

MC78T12 12V 3A Voltage Regulator.

+12V 3A fixed voltage regulator. TO-220 package.

The MC78T12 is a voltage regulator integrated circuit that is designed to provide a stable output voltage of 12 volts with a maximum current rating of 3 amperes. It is part of the 78xx series of voltage regulators, which are commonly used in electronic circuits to provide a fixed and regulated voltage.

The MC78T12 voltage regulator is a linear regulator, which means that it works by continuously adjusting the resistance of a series pass transistor to maintain a constant output voltage. It is capable of accepting input voltages ranging from 14 volts to 35 volts, and it provides a dropout voltage of approximately 2 volts, meaning that the input voltage must be at least 2 volts higher than the output voltage in order for the regulator to operate properly.

The MC78T12 voltage regulator also includes a number of built-in protection features, such as thermal shutdown, overvoltage protection, and short-circuit protection, which help to ensure safe and reliable operation in a variety of applications.

The MC78T12 is commonly used in power supply circuits, battery charging circuits, and other applications where a stable and regulated 12-volt output voltage is required.
