1. From 5~100% load, nominal input, 20 MHz bandwidth oscilloscope, with 10 µF tantalum and 1 µF ceramic capacitors on the output. From 0~5% load, ripple and noise is
<5% Vo.
2. Measured at nominal input voltage, full load.
3. All specifications are measured at Ta=25°C, humidity < 75%, nominal input voltage, and rated output load unless otherwise specified.

Tested at input voltage range and full load.
At 0~5% load, the max output voltage accuracy for the ±5 & ±9 Vdc output models is ±5%.
At 0~100% load, the max load regulation is ±5%.
Unbalanced loads should not exceed ±5%. If ±5% is exceeded, the product performance cannot be guaranteed.
Value is based on full load. At loads <50%, the switching frequency decreases with decreasing load.

APPLICATION CIRCUIT
This series has been tested according to the following recommended circuits (Figures 1 & 2) before leaving the factory.
If you want to further reduce the input and output ripple, you can increase the input and output capacitors or select
capacitors of low equivalent impedance provided that the capacitance is less than the maximum capacitive load of the
