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)

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 1.4V higher than

VOUT in order for the device to

regulate properly.

VOUT

The output of the regulator. A

minimum of 10uF capacitor (0.15Ω

≤ ESR ≤ 20Ω) must e connected

from this pin to ground to insure

stability.
