The DUR01 series are the standard building blocks for on-board distributed power
systems. They are ideally suited to providing single and dual supplies on primarily
digital boards with added benefit of galvanic isolation to reduce switching noise. All
of the rated power may be drawn from a single pin provided the total load does not
exceed 1 watt.

The DUR01 series required a minimum 10% loading on the output to
maintain specified regulation. Operation under no-load condition will not
damage these devices, however they may not meet all listed
