Minimum load
The minimum load to meet datasheet specifi cation is 10% of the full rated load across the specifi ed input voltage range. Lower than 10% minimum loading will result in
an increase in output voltage, which may rise to typically double the specifi ed output voltage if the output load falls to less than 5%.
Capacitive loading and start up
Typical start up times for this series, with a typical input voltage rise time of 2.2μs and output capacitance of 10μF, are shown in the table below. The product
series will start into a capacitance of 47μF with an increased start time, however, the maximum recommended output capacitance is 10μF.
Ripple & Noise Characterisation Method
Ripple and noise measurements are performed with the following test confi guration.
