APPLICATION NOTES
Output Capacitors
The NCS6 series does not require output capacitors to meet datasheet specification. To meet datasheet specification, total output capacitance should not exceed:
Output Voltage (V) Output Capacitance (µF)
3.3 470
5 470
12 220
15 220
Minimum Load
The minimum load to meet full datasheet specification is 10% of the full rated load across the specified input voltage range.
Between 0% and 10% output loading, the positive output voltage will remain within data sheet specification however, output ripple and noise will increase as well as a
decrease in accuracy on negative outputs.
