Description
This series of fixed-voltage monolithic 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. In addition, they can be used with power-pass elements to make high-current voltage regulators.Each The internalof these regulators can deliver up to 1.0 A of output current. limiting and termal shutdown features of these regulators make them essentially immune to overload.
