Notes: Derating Curve
1. Output load regulation is specifi ed for a load change of
20% to 100%.
2. When measuring output ripple & noise, it is recom-
mended that an external ceramic capacitor (0.33 µF
typ.) be placed from the +VOUT to the -VOUT pins.
3. Free air convection is typically 20 LFM. The units should
not be operated in still air (0 LFM).
4. Operation at no-load will not damage the unit, but they
may not meet all specifi cations.
5. It is recommended that a fuse be used on the input of a power
supply for protection. See the Model Selection table above for
the correct rating.
