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.
