Notes:
1. Output load regulation is specified for a load change of 20% to 100%.
2. When measuring output ripple, it is recommended that an external 0.33 µF ce-
ramic capacitor be placed from the +Vout pin to the -Vout pin for single output
units and from each output to common for dual output units.
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. How-
ever, 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.
