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 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. 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.
