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 minimum of 10uF capacitor must be

connected from this pin to ground to insure stability.

The input pin of regulator. Typically a large storage capacitor 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 response. This pin must always be 1.3V higher than

Vout in order for the device to regulate properly.
