Adjustable (Ground only for fixed mode)
A resistor divider from this pin to the V
(Ground only for Fixed-Mode).
The output of the regulator. A minimum of 10uF (0.15Ω ≤ ESR ≤ 20Ω) 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 1.4V
(1.3V) higher than V
