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-

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.
