Design Reference
1. 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, see Fig.3.
Moreover, choosing a suitable filter capacitor is very important, start-up problems may be caused if the capacitance is too large. Under the
condition of safe and reliable operation, the recommended capacitive load values are shown in Table 1.
