Notes  
1. 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 outputs.  
2. Effect on –Vout for the following conditions, percentages are of total power:  
+Po = 50% to 10% and –Po = 50%  
3. Indefinite short circuit protection not guaranteed above 125°C (case)  
4. Recovery time is measured from application of the transient to point at  
which Vout is within regulation.  
5. Response of either output with the opposite output held at half of the total  
output power.  
6. Input step transition time >10µs.  
+Po = 50% and –Po = 50% to 10%  
7. Input step transition time <100µs.
