fixed-voltage monolithic integrated-circuit voltage regulators - Estek Electronics
Description
7805B
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.
