To meet datasheet specification, total output capacitance should not exceed: Output Voltage (V) Output Capacitance (F) 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. www.murata-ps.com/support KDC NCS6C.D04 Page 2 of 10
