Typical Application Circuits
M-78B-Z
C1: A low ESR capacitor is required to keep the noise of the converter to a minimum. Ceramic capacitors are recommended
with typical value is 10µF / 25V.
C2: Installation of C2 is recommended with typical value of 22µF / 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 parallel operation.
