Typical Application Circuit If it is required to further reduce input and output ripple, a filter capacitor may be connected to the input and output terminals. Moreover, choosing a suitable filter capacitor is very important, start-up problems may arise if capacitance is too large. Under the condition of safe and reliable operation, recommended capacitive load values are shown in table below.
