APPLICATION CIRCUIT

EMC RECOMMENDED CIRCUIT

Table 3

If you want to further reduce the input and output ripple, a filter capacitor may be connected to the input and output

terminals (Figure 1) provided that the capacitance is less than the maximum capacitive load of the model, otherwise start-

up problems may be caused if the capacitance is too large.
