Such an output capacitor - in conjunction with its finite ESR (!) - helps to improve the stability of the regulator (which is a closed-loop system).I still recommend putting 0.1μF ceramic caps on the input and output pins of the regulator.
It's to stop high frequency oscillations happening isn't it?Sorry about thread jack
But what is the purpose of the bypass cermaic cap? ??
