RECOMMENDED CIRCUIT
All the CTDD3220DF-D1.5K-5M Series have been tested according to the following recommended testing circuit before
leaving factory. This series should be tested under load. Never be tested under no load (See figure 1 & 2). If you want
to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR.
However, the capacitance should not be too high. (See table 1)
