Notes
1. guaranteed by design, not tested.
2. unit will shut down above approximately 45 V 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 V
OuT
is within 1% of final value.
4. Tested on release from inhibit.
5. Shall not compromise DC performance.
