Notes:
1. Guaranteed by design, not tested.
2. Unit will shut down above approximately 45V but will be undamaged
and will restart when voltage drops into normal range.
3. Recovery time is measured from application of the transient to point at
which Vout is within 1% of final value.
4. Transition time ≥ 10 μs.
