3-TERMINAL POSITIVE VOLTAGE REGULATORS
G3U78XXA
Description
The G3U78XXA series of fixed-voltage monolithic integrated-circuit voltage regulators 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. 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.
Features
Ԧ5V, 6V, 8V, 9V, 10V, 12V, 15V, 18V, 24V output voltage available
ԦInternal Thermal Overload Protection
ԦHigh Power Dissipation Capability
ԦInternal Short-Circuit Current Limiting
ԦNo External Components
ԦOutput Transistor Safe-Area Compensation
