Description
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.

FEATUREs:
◾ ±5% VOUT tolerance over entire temperature range
◾ Greater than 1A output current capability
◾ Internal thermal overload protection
◾ Internal short-circuit current limit
◾ Output capacitor not essential for stability
◾ Full Military temperature range
◾ Negative voltage complement is 7909
