Notes:
1. Guaranteed by design, not tested.
of that total is available from either output provided the other output
maintains a minimum of 15% the total power used.
7. Effect on negative Vout from 50%/50% loads to 70%/30% or 30%/70%
loads.
2. Short circuit is measured with a 10 mΩ ( 10%)resisitive load.
3. Time to settle to within 1% of Vout.
4. Transition time > 10 μs
5. Output voltage for dual output models is measured at half load.
8. Tested on release from inhibit.
6. The maximum specification is the total output current/power. Up to 70%
