12V Voltage Regulator - L7812

This is a 12V Voltage Regulator that restricts the voltage output to 12V and draws 12V regulated power supply. The 7812 is the most common, as its regulated 12-volt supply provides a convenient power source for most TTL components. L7812 is a series of 78XX voltage regulators. For ICs within the family, the xx is replaced with two digits, indicating the output voltage (for example, the 7805 has a 5-volt output, while the 7812 produces 12 volts).

The purpose of a voltage regulator is to keep the voltage in a circuit relatively close to the desired value. Voltage regulators are one of the most common electronic components since a power supply frequently produces a raw current that would otherwise damage one of the components in the circuit.
