This series should be tested under load. Never be tested under no load (see Figure 1). DC DC Vin GND +Vout 0V Cin Vin GND +Vout 0V Cin DC DC -Vout Dual Output Single Output (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 should not be too high (Table 1).
