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 may cause damage to the unit.

3. These converters will oper-

ate without external com-

ponents. However, when

measuring output ripple,

it is recommended that an

external ceramic capaci-

tor be placed from the

+Vout pin to the -Vout

pin. 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 protection. See the Model Selection

table above for the correct rating.
