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, on, the recommended capacitive load values are shown in Table 1.

Output load requirements When using, the minimum load of the module output should not be less than 1% of the nominal load. In order to meet the performance parameters of this datasheet, please connect a 1% dummy load in parallel at the output end, the dummy load is generally a resistor, Please note that the resistor needs to be used in derating.
