Notes:

1. Output load regulation is specified for a load change of 10% to 100%.

2. These units should not be operated with a load under 10% of full load. Operation

at no-load will not damage the unit, but they may not meet all specifications.

3. These converters will operate without external components. However, when

measuring output ripple,

it is recommended that an

external 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. An input capacitor will enhance stability over temperature and

input line variations. Recommended capacitor values are given in the table above.

For applications requiring very low output noise levels, a simple LC filter should

be effective.

4. It is recommended that a fuse be used on the input of a power supply for protec-

tion. See the Model Selection table above for the correct rating.
