2. Transient recovery time is measured to within 1%
error band for a step change in output load of 75%
to 100%.

Exceeding these values can damage the module. These are not continuous
operating ratings.
3. Ripple & Noise measurement bandwidth is 0-20
MHz.
4. These power converters require a minimum
output loading to maintain specified regulation.
5. Operation under no-load conditions will not
damage these devices; however they may not
meet all listed specifications.
