Notes:

Derating Curve

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 ap-

plications 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.
