Notes
1. Guaranteed by design, not tested.
2. Up to 90% of the total output current/power is available from either output providing
the positive output is carrying at least 10% of the total output power.
3. Operation is limited below 16 V (see Figure 22).
4. Effect on negative Vout from 50%/50% loads to 80%/20% or 20%/80% loads.
5. Effect on negative Vout from 50%/50% loads to 90%/10% or 10%/90% loads. See
Figure 20.
6. Indefinite short circuit protection not guaranteed above 125°C case.
7. Recovery time is measured from application of the transient to point at which Vout
is within 1% of final value.
8. Tested on release from inhibit.
