Notes:
6. The maximum specification is the total output current/power. Up to 70%
of that total is available from either output provided the other output
maintains a minimum of 15% the total power used.
1. Load fault conditions are measured with a resistive load.
2. Short circuit is measured with a 10 m W ( 10%) load.
3. Time to settle to within 1% of Vout.
7. Cross regulation percentages are for the following conditions:
4. Transition time > 10 µs
5. Output voltage for dual output models is measured at half load.
+Po = 30% and –Po = 70%
+Po = 70% and –Po = 30%
+Po = 10% and –Po = 50%
+Po = 50% and –Po = 10%
