LM7805CT - LM7812CT- LM7824CT Positive Voltage Regulators
GENERAL DESCRIPTION
This series of fixed-voltage integrated-circuit voltage regulators is 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 1.5A of output current. The internal current-limiting and thermal-shutdown features of these regulators essentially make them immune to overload. In addition to use as fixed-voltage regulators, these devices can be used whit external components to obtain adjustable output voltages and currents, and also can be used as the power-pass element in precision regulators. Compliance to RoHS.
FEATURES
• • • • • 3-Terminal Regulators Output Current up to 1.5A Internal Thermal-Overload Protection Output Transistor Safe-Area Compensation With TO220 package
