Name

Description

ADJ

(GND)

A resistor divider from this pin to the VOUT pin

and ground sets the output voltage. (Ground

only for Fixed-Mode)

VOUT

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.

VIN

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

1.2V higher than VOUT in order for the device

to regulate properly.
