This pin is the positive side of the reference that allows remote load sensing to achieve excellent load
regulation. A minimum of 10uF capacitor must be connected from this pin to ground to insure stability.
A resistor divider from this pin to the Vout pin and ground sets the output voltage.
(GND only for fixed mode)
The output of the regulator. A minimum of 100uF capacitor must be connected from this pin to ground
to insure stability.
This pin is the supply pin for the internal control circuit as well as the base drive for the pass transistor.
This pin must always by higher than the Vout pin in order for the device to regulate. A minimum of
100uF capacitor must be connected from this pin to ground to insure stability.
The input of the 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 higher than Vout in order for the device to regulate.
