DESCRIPTION: DC switching regulator, non-isolated
description
The V78XX series of switching regulators is
designed as a drop in replacement for 78XX
linear regulators. Because the V78XX series
features high efficiency under all line
conditions, there is no need for a heatsink.
Built-in short-circuit and over-temperature
protections ensure very rugged operations.
Additionally, low ripple and noise
performance makes the parts useful in a wide
range of applications.
