The REC3-SR/DR series is a low cost converter containing a built in linear regulator to
give a regulated, load independent constant voltage output. The converter is designed to
run from a regulated supply and is typically used to provide an isolated output or to
generate dual rails from a single rail supply. The converters can deliver 140% rated power
for short periods of time to cope with applications with large capacitive loads or high start
up currents.

Maximum capacitive load is defined as the capacitive load that will allow start up in under 1 second without damage to the converter
The REC3-R series requires a minimum of 10% load on the output to maintain specified regulation. Operating under no-load
conditions will not damage these devices; however, they may not meet all listed specifications.
