Output load regulation is specified for a load change of 20% to 100%. 2. When measuring output ripple & noise, it is recommended 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 specifications. 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.
