SECOS S3U7805-B

S3U78xx-B Series
3-Terminal
Positive Voltage Regulator
Elektronische Bauelemente
RoHS Compliant Product
A suffix of “-C” specifies halogen and lead-free
DESCRIPTION
The S3U78xx-B 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 1A of output current.
The internal current limiting and thermal shutdown features
of the regulators make them essentially immune to overload.
