PART NUMBER: V78XX-500 series
description
The V78XX series of switching regulators are
designed to replace 78XX linear regulators,
with the objective of drop-in replacement
without the need for a heatsink, because the
V78XX series features high efficiency under
all line conditions. 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.
