Pin#

Description

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 pin of regulator. A min. of 10μF capacitor must be connected from this pin

to ground to insure stability.

VIN

I

3

The input pin of regulator. Typically a large storage capacitor is connected from this

pin to ground to insure that the input voltage does not sag below the min. 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.
