DESCRIPTION
O
C
I
This series of fixed-voltage monolithic integrated-circuit
voltage regulators designed for a wide range of
applications. These applications include on-card
TO-220
regulation for elimination of noise and distribution
WS7805CV
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.
