8.1.1.5 CO and CO3

CO should generally be no smaller than 10 µF. Experimentation is usually necessary to determine the minimum value for CO, as the nature of the load may require a larger value. A load which creates significant transients requires a larger value for CO than a fixed load.

CO3 is a small value ceramic capacitor to further suppress high frequency noise at VOUT. A 47 nF is recommended, located close to the LM3100.
