| WS7805 ! ! ! ! ! ! ! 3-Termainal Regulators Output Current Up to 1.5 A No External Components POSITIVE-VOLTAGE REGULATORS TO-252 WS7805DP Internal Thermal Overload Protection High Power Dissipation Capability Internal Shot-Circuit Current Limiting Output Transistor Safe-Area Compensation O IC (TO-252) DESCRIPTION This 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.
