SERIES: V78XX-1000
DESCRIPTION: DC SWITCHING REGULATOR,
NON-ISOLATED
DESCRIPTION
The V78XX switching regulator series
is designed to be a high efficiency
drop-in replacement for 78XX linear
regulators. Unlike linear regulators,
the V78XX series does not require a
heatsink, creating a much more
compact solution. Built-in short-circuit
and over-temperature protections
ensure very rugged operations.
Additionally, low ripple and noise
performance make the parts useful in a
wide range of applications.
FEATURES
•efficiency up to 97%
•1A current output
