S3U78xx
Elektronische Bauelemente 3-Terminal Positive Voltage Regulator
RoHS Compliant Product A suffix of "-C" specifies halogen and lead-free
DESCRIPTION
The S3U78XX 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 1A of output current. The internal current limiting and thermal shutdown features of the regulators 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
