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 4.7μF capacitor (0.15 ? ≤ ESR ≤ 0.5 ? ) 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 V OUT in order for the device to regulate
properly. A minimum of 4.7μF capacitor (0.15 ? ≤ ESR ≤ 0.5 ? ) must be connected from this pin to
ground to insure stability.
