FUNCTION
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 (0.15Ω
≤ ESR ≤ 20Ω) 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 1.3V higher than Vout in order for the device to
regulate properly.
