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

IEC/EN-60950-1 + A2 Safety.

Optional Diode Protection Circuit

Optional Protection 1:

Add a blocking diode to Vout if

current can flow backwards into

the output, as this can damage

the converter when it is powered

down.

The diode can either be fitted

across the device if the source is

low impedance or fitted in series

with the output (recommended).
