DESIGN REFERENCE

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.1Moreover, choosing a suitable

filter capacitor is very important, start-up problems may be caused if the capacitance is too large. Under thecondition of safe and reliable operation, the

recommended capacitive load values are shown in Table 1.
