1. The input capacitor Cs > 200nF is necessary for the smoothing of line disturbances. The output capacitor
C01 > 100nF is necessary for the stability of the regulation loop. In order to dampen output voltage
oscillations during high load current surges, it is recommended an additional electrolytic capacitor C02 >
10µF to be placed at the output pin.

1. The curve which describes the minimum ESR is derived from characterization data on the regulator with
connected ceramic capacitors which feature low ESR values (at 100 kHz). Any capacitor with further lower
ESR than the given plot value must be evaluated in each and every case.
