Description
Adj A resistor divider from this pin to the Vout pin and ground sets the output voltage. (GND
(GND)
only for fixed mode)
This pin is the positive side of the reference that allows remote load sensing to achieve

I excellent load regulation. A minimum of 10uF 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.
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 be higher than the Vout pin in order to regulate the
device. A minimum of 100uF capacitor must be connected from this pin to ground to
insure stability.
