Notes
1. guaranteed by design, not tested.
2. Operation is limited below 16V (see Figure 22).
3. Indefinite short circuit protection not guaranteed above 125°C case.
4. Recovery time is measured from application of the transient to point at which Vout
is within 1% of final value.
5. Tested on release from inhibit.
