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.
