The 7908 8V fixed 3-terminal negative 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 7908

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.
