Notes
1. Guaranteed by characterization test and/or analysis. Not a production test.
2. Up to 70% of the total output power is available from either output providing the
opposite output is simultaneously carrying 30% of the total output power. Each
output must carry a minimum of 30% of the total output power in order to maintain
regulation on the negative output.
3. Balanced loads.
4. Effect on –V_out for the following conditions, percentages are of total power:
+P_o = 50%, –P_o = 10%; +P_o = 10%, –P_o = 50%
+P_o = 70%, –P_o = 30%; +P_o = 30%, –P_o = 70%
All conditions are referenced to balanced loads of 50%/50%.

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
V_out is within regulation.
7. Response of either output with the opposite output held at half of the total output
power.
8. Step transition time >10 µs.
9. Step transition time 100 µs ±20%.
10. Tested on release from inhibit.
11. Applies to each output.
