1. guaranteed by design, not tested.
2. The specified max current is available from either output.
3. 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.
4. Operation is limited below 16 V (see Figure 22).
5. Effect on the negative output under the following conditions:
+Pout 20% to 80%; –Pout 80% to 20%
6. Effect on the negative output under the following conditions:
+Pout 50%; –Pout 10% to 50%
7. Tested with 6800 pF ceramic bypass capacitors connected externally from
input common to case.
8. Indefinite short circuit protection not guaranteed above 125°C case temper-
ature.
9. Recovery time is measured from application of the transient to point at
which Vout is within 1% of final value.
10. Transition time ≥ 10 µs.
