NEGATIVE VOLTAGE REGULATOR
GM79LXX
Description
The GM79LXX series of fixed-voltage monolithic integrated circuit voltage regulators are designed for a wide
range of applications. These applications include on-card regulation for elimination of noise and distribution
problems associated with single-point regulation. In addition, they can be used with power-pass elements to
make high current voltage regulators. Each of these regulators can deliver up to 100mA of output current. The
internal limiting and thermal shutdown features of these regulators make them essentially immune to overload.
When used as a replacement for a Zener diode-resistor combination, an effective improvement in output
impedance can be obtained together with lower-bias current.
