Adj (GND)

I

1

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

(Ground only for fixed mode)

Vout

O

2

The output of the regulator. A minimum of 10 F capacitor (0.15 Ł ESR 20 Ł )

must be connected from this pin to ground to insure stability.

Vin

I

3

The input pin of regulator .Typically a large storage capacitor(0.15 Ł ESR 20 Ł )

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 1.3V higher than Vout in order for the device to regulate properly.
