Typical Application If it is required to further reduce input and output ripple, a filter capacitor can be connected to the input and output terminals (see figure below). Moreover, choosing suitable filter capacitor is very important, start-up problems may be caused by too large capacitance. To ensure modules are running well, the recommended capacitive load values are shown in table below. Recommended Capacitive Load Value Table Vin (VDC) Cin (µF) Vout (VDC) Cout (µF) 5 4.7 3.3/5 10 - - 9/12 2.2 - - 15/24 1 2.
