LM7809 / 7809 Voltage Regulator is a fixed-voltage integrated-circuit voltage regulator designed for a wide range of applications. The L7809 voltage regulator provides 9V Positive voltage as output and can provide local on-card regulation, eliminating the distribution problems associated with single-point regulation. Although designed primarily as a fixed voltage regulator, but it can be used with external components to obtain adjustable voltage.
