Description
The R-78xx-Series high efficiency switching regulators are 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.This R-78xx-0.5 is fully
certified to EN 55022 (Emissions), and EN55024 (Immunity) EMC Standards and for EN-60950-1 Safety.
