The output of the regulator. A minimum of 10uF capacitor (0.15Ω ≤ ESR ≤ 20Ω)
must be connected from this pin to ground to insure stability.
The input pin of regulator. Typically a large storage capacitor is connected from
I
3 this pin to ground to insure that the input voltage does not sag below the
minimum dropout voltage during the load transient response.
