DESIGN CONSIDERATIONS
1) Recommended circuit
All the URA_(X)D-10WR2 & URB_(X)D-10WR2 Series have been tested according to the following recommended testing circuit before leavin
factory (see Figure 5).
If you want to further decrease the input/output ripple, you can increase a capacitance properly or choose capacitors with low ESR, but the
greatest capacitance of its filter capacitor must less than the Max. Capacitive Load.
