notes
1. guaranteed by design, not tested.
2. For MHF+281r9, load regulation is tested from a 10 ma load to full load.
3. indefinite short circuit protection not guaranteed above 125°C (case).
4. recovery time is measured from application of the transient.
to the point at which v
out
is within regulation.
5. Step transition time >10 µs.
6. Step line is 20 - 32 - 20 vdC for MHF+281r39S.
