SG78XX
3-Terminal Positive Voltage Regulator
Description
The SG78XX series of fixed-voltage monolithic intergratedcircuit 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 1A of output current. The internal current limiting and thermal shutdown features of there trgulators make them essentially immune to overload.
Features
*5V,6V,8V,9V,10V,12V,15V,18V,24V Output Voltage Available *Output Transistor Safe-Area Compensation *No External Components *Internal Thermal Overload Protection *Internal Short-Circuit Current Limiting *High Power Dissipation Capability
