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.
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.

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.
