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.

Notes
Note 1: Maximum capacitive load is defined as the capacitive load that will allow start up in under 1 second without damage to the converter
Note 2: 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.
