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 the point at which
Vout is within 1% of final value.
4. Transition time 100 µs ±20%.
5. Tested on release from inhibit.
6. Shall not compromise DC performance.
