The DU1P0 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.
