Description

TO263/252

Adj

(GND)

1

Adjustable (Ground only for fixed version)

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

output voltage.

VOUT

2

The output of the regulator. A minimum of 100uF (0.15Ω ≤ ESR ≤

10Ω) capacitor must be connected from this pin to ground to insure

stability.

VIN

3

The input pin of regulator. Typically a large storage capacitor (0.15Ω

≤ ESR ≤ 10Ω) 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.
