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 10u F 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...
