regulator, non-isolated
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.
