Adj (GND) I 1
A resistor divider from this pin to the V
OUT
pin and ground sets the output voltage (Ground only for
Fixed-Mode).
V
OUT
O 2
The output of the regulator. A minimum of 4.7µF capacitor (0.05 Ω ≤ ESR ≤ 0.5Ω) must be connected
from this pin to ground to insure stability. For improved ac load response a larger output capacitor is
recommended.
V
IN
I 3
The input pin of regulator. Typically a large storage capacitor (0.05 Ω ≤ ESR ≤ 0.5Ω) is connected from
this pin to ground to ensure 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 V
OUT
in order for the
device to regulate properly.

Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only; functional
operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be affected by exposure to
absolute maximum rating conditions for extended periods of time.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling and
transporting these devices
