Notes
1. Guaranteed by qualification test and/or analysis. Not an in-line test.
2. Up to 4 watts (80% of full power) is available from either output providing the
opposite output is carrying 20% of total power.
3. Shows regulation effect on the minus output during defined cross loading
conditions. See “Figure 24” and “Figure 25” on page 11.
4. An external 2 µH inductor, added in series to the input, is necessary to maintain
specifications.
5. Indefinite short circuit protection not guaranteed above 125°C (case).
6. Recovery time is measured from application of the transient to point at which
Vout is within 1% of Vout at final value.
7. Transition time >10 µs.
