FUNCTION

A resistor divider from this pin to the Vout pin and ground sets the

output voltage. (Ground only for Fixed-Mode)

The output of the regulator. A capacitor with a minimum value of

10µF, 0.15Ω ≤ ESR ≤ 1Ω) must be connected from this pin to

ground to ensure stability.

The input pin of regulator. Typically a large storage capacitor

(0.15Ω ≤ ESR ≤ 1Ω) is connected from this pin to ground to

ensure that the input voltage does not sag below the minimum

dropout voltage during the load transient response. This pin must

always be 1.3V higher than Vout in order for the device to

regulate properly.
