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. 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 table above for the correct rating.
