Notes
1. Up to 13.5 watts, 90% (9.6W, 80% for 2805D) of the total output power is
available from either output providing the opposite output is simultaneously
carrying 10% (20% for 2805D) of the total output power. Each
output must carry a minimum of 10% (20% for 2805D) of the total output
power in order to maintain regulation on the negative outputs.
2. Effect on –Vout for the following conditions:
+Po = 50% to 10% and –Po = 50%
+Po = 50% and –Po = 50% to 10%
3. Indefinite short circuit protection not guaranteed above 100°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 >10s.
7. Input step transition time <100s.
