Function
A resistor divider from this pin to the V OUT pin and ground sets the output voltage (Ground only for Fixed-
Mode).
The output of the regulator. A minimum of 10uF capacitor (0.15 ? ≤ ESR ≤ 20 ? ) must be connected from this
pin to ground to insure stability.
The input pin of regulator. Typically a large storage capacitor (0.15 ? ≤ ESR ≤ 20 ? ) 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 V OUT in order for the device to regulate properly.
