NOTES:
1. add a 0.1碌F ceramic capacitor and a 10碌F E.L. capacitor to output for ripple
and noise measuring @20MHz BW.
2. voltage accuracy is set at full load
3. line regulation is measured from 100VAC to 240VAC with full load.
4. load regulation is measured from 60% to 100% full load and from 60% to 20%
full load (60% 鹵40% full load).
