3-TERMINAL NEGATIVE VOLTAGE REGULATORS

Description

The G

I79XX series of fixed-voltage monolithic integrated-circuit voltage regulators are designed to complement

Series G

I78XX 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.

Features
