C1: A low ESR capacitor is required to keep the noise of the converter to a minimum.
Ceramic capacitors are recommended, but tantalum or electrolytic may be used. Typical value is 22µF / 50V.
C2: Installation of C2 is recommended but optional. Typical recommended value is 100µF / 25V electrolytic.
NOTE: This part is not designed for parallel operation.
