C. The resistor value is calculated as R = 4/0.1 = 40
. A
resistor power rating of 400 mW or greater may be used.
Bypass Capacitors
The high frequency performance of the ADM663A/ADM666A
may be improved by decoupling the ouput using a filter capaci-
tor. A capacitor of 0.1
μ
F is suitable.

An input capacitor helps reduce noise, improves dynamic per-
formance and reduces the input dV/dt at the regulator input. A
suitable input capacitor is 0.1
μ
