3-TERMINAL NEGATIVE VOLTAGE REGULATORS

Description

The G3U79XX series of fixed-voltage monolithic integrated-circuit voltage regulators are designed to

complement Series G3U78XX 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 1.0 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.
