Notes:

1. Output load regulation is specified for a load change of 10% to 100%.

2. When measuring output ripple, it is recommended that an external ceramic

capacitor (approx approx 1

µF to 10 µF) be placed from each output to

common.

3. These units should not be operated with a load under 10% of full load.

Operation at no-load may cause damage to the unit.

4. These converters are specified for operation without external components.

However, in some applications the addition of input/ouput capacitors will

enhance stability and reduce output ripple. Recommended capacitor values

are:

For applications requiring very low output noise levels, a simple LC filter

should be effective.

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.
