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 a short circuit input current of typically only 7mA round off the specifications of this versatile converter
series.
This R-78xx-0.5 is fully certified to EN 60601-1-2 (Medical Equipment), EN 55022 (Emissions), and
EN55024 (Immunity) EMC Standards.
