Description

Adj

(GND)

Adjustable (Ground only for fixed version)

A resistor divider from this pin to the VOUT pin and ground sets the output voltage.

VOUT

The output of the regulator. A minimum of 100uF aluminum electrolytic capacitor

(ESR ≤ 5Ω) or 10uF MLCC must be connected from this pin to ground to insure

stability.

VIN

The input pin of regulator. Typically a large storage capacitor (ESR ≤ 5Ω) 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.
