9V Voltage Regulator - L7809

This is a 9V Voltage Regulator that restricts the voltage output to 9V and draws 9V regulated power supply. The 7809 is the most common, as its regulated 9-volt supply provides a convenient power source for most TTL components. L7809 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 7812 has a 12-volt output, while the 7805 produces 5 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.
