This series should be tested under load. Never be tested under no load (see Figure 1). Dual Output Vin Cin +Vo Cout DC DC Cout 0V -Vo GND Single Output Vin Cin +Vo DC DC Cout GND 0V (Figure 1) If you want to further decrease the output ripple, you can increase capacitance properly or choose capacitors with low ESR. However, the capacitance can’ t exceed the maximum capacitor load in the list. ② Recommended capacitance To ensure these series can operate efficiently and reliably, t he recommended capacitance of input and output sees the below table.
