C1: A low ESR capacitor is required to keep the noise of the converter to a minimum.Ceramic capacitors are recommended
withtypical value is 10µF / 25V.
C2: Installation of C2 is recommended withtypical value of22µF / 16V ceramic for 5V and 6.5V output signal and 22µF / 6.3V
ceramic for 2.5V and 3.3V output signal.
NOTE: This part is not designed for paralleloperation.
