ISSUED DATE :2005/04/07 REVISED DATE :2005/12/06C GU78XXA 3-TERMINAL POSITIVE VOLTAGE REGULATORS Description The GU78XXA 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 5V, 6V, 8V, 9V, 10V, 12V, 15V, 18V, 24V output voltage available Internal Thermal Overload Protection High Power Dissipation Capability Internal Short-Circuit Current Limiting No External Components Output Transistor Safe-Area Compensation Package Dimensions REF.
