Mode).

O

The output of the regulator. A minimum of 10uF capacitor (0.15

Ω ≤ ESR ≤ 20Ω) must be connected from this

pin to ground to insure stability.

I

The input pin of regulator. Typically a large storage capacitor (0.15

Ω ≤ ESR ≤ 20Ω) is connected from this pin

to ground to insure that the input voltage does not sag below the minimum dropout voltage during the load
