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 0.33 µF ceramic capacitor be placed from

each output to common.

3. During operation, care must be taken not to exceed the specified input range of the unit or to allow the output

load to drop below the specified minimum (10% of full load). Operating the unit under either of these conditions

could cause damage to the unit.

4. These converters are specified for operation without external components. However, in some applications the

addition of input/output 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.
