Notes
1. Input current measured at nominal input voltage.
2. From 10% to 100% load.
3. When one output is set at 100% and the other varied between 25% and
100% load.
4. Measured with 20 MHz BW and 1 µF ceramic capacitor across output rails.
5. External input capacitor required, Nippon Chemi-Con KY series, 220 µF/100 V
or equivalent.
