For the best line-transient performance, decouple the
input with a 0.1µF ceramic capacitor as shown in the
Typical Operating Circuit . Locate the capacitor as
close to the device pin as possible. Where transient
performance is less important, no capacitor is neces-
sary.
The MAX6120 performs well without an output decou-
pling capacitor. If your application requires an output
charge reservoir (e.g., to decouple the reference from
the input of a DAC), then make sure that the total output
capacitive load does not exceed 10nF.
