If the actual output power is small, please connect a resistor at the output end in parallel to increase the load. 2. Recommended circuit This series has been tested according to the following recommended testing circuit before leaving the factory. This series should be tested under load (see Figure 3). If you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR (see Table 3). However, the capacitance must not exceed the maximum capacitive load or a start-up problem might arise (see Table 4). Figure 3 ED 1.
