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 Vout is within 1% of final value.
4. Transition time > 10 µS.
5. Tested on release from inhibit.
6. Shall not compromise DC performance.
7. SMFL283R3S current and power are at 25°C only.
