For the dual output board, the second output relies on the main output for regulation. 10%

regulation is typical for load and cross regulation for a swing of 10% to 100% of the output’s

maximum load. The ripple on the first output is very low because of the pie filter (L2, C10)

that eliminates the switching ripple and the spikes.
