Notes

1. Guaranteed by characterization test and/or analysis. Not a production test.

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 opposite output is carrying at least 10% of the total output power.

4. Operation is limited below 16 V (see Figure 22 on page 10).

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%. See Figure 21 on page 10.

7. Tested with 6800 pF ceramic bypass capacitor connected externally from input

common to case.

8. Indefinite short circuit protection not guaranteed above 125°C case temperature.

9. Recovery time is measured from application of the transient to point at which

VOUT is within 1% of final value.

10. Tested on release from inhibit.
