voltage (Ground only for Fixed-Mode).

O

2

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.

I

3

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

device to regulate properly.
