LINE
LOAD
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.
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.
