The 7809 9V fixed 3-terminal positive voltage regulator

delivers up to 1.5A of output current with adequate

heat-sinking. The device is equipped with internal

limiting, safe-area compensation + thermal shutdown

features for overload immunity. The 7809 can be used

with external components to obtain adjustable voltages

or currents & can also be used as the power-pass

element in precision high-current voltage regulators.

No external components are needed other than to

enhance performance or increase design flexibility.
