GU78XX
Description
3-TERMINAL POSITIVE VOLTAGE REGULATORS
The GU78XX 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 amperes of output current.
The internal current limiting and thermal shutdown features of these regulators make them essentially immune
to overload.
Features
&
6V, 8V, 9V, 10V, 12V, 15V, 18V, 24V output voltage available
5V,
&Internal Thermal Overload Protection
&High Power Dissipation Capability
&Internal Short-Circuit Current Limiting
&No External Components
&Output Transistor Safe-Area Compensation
