3-TERMINAL NEGATIVE VOLTAGE REGULATORS
GE79XXA
Description
The GE79XXA series of fixed-voltage monolithic integrated-circuit voltage regulators are designed to
complement Series GE78XXA in a wide range of applications. These applications include on-card regulation
for elimination of noise and distribution problems associated with single-point regulation. Each of these
regulators can deliver up to 1.5 amperes of output current. The internal current limiting and thermal shutdown
features of these regulators make them essentially immune to overload. In addition to use as fixed-voltage
regulators, these devices can be used with external components to obtain adjustable output voltage and
current and also as the power pass element in precision regulators.
