Adjustable (Ground only for fixed mode)
A resistor divider from this pin to the V
voltage (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 (0.15Ω ≤
ESR ≤ 20Ω) 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
