Notes:
1. All measurements should be made directly at the terminals of the
power supply
2. Minimum Load is NOT required for proper operation. However, auxil-
iary outputs should be reduced as a function of primary output minimum
load or load reugulation will be higher.
3. Load Regulation measured from 20% to full load. All other outputs at
nominal load.
4. Output noise measured directky at pins at nomimnal load with 0.1uF
and 10uF capacitors, pk-pk @ 20MHz bandwidth.
