Description

General part information

R-78 Series

The R-783.3-0.5 is a 1-output non-isolated PoL Switching Regulator, ideally suited to replace 78xx linear regulators and are pin compatible. The efficiency of up to 97% means that very little energy is wasted as heat so there is no need for any heat sinks with their additional space and mounting costs. Low ripple and noise figures and short-circuit, overload and over-temperature protection round off the specifications of this versatile converter series.
