Pin Name I/O Pin #

Description

Adj (GND) I

Adjustable (Ground only for fixed mode)

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

(Ground only for Fixed-Mode).

The output of the regulator. A minimum of 10uF (0.15Ω ≤ ESR ≤ 20Ω) capacitor must

be connected from this pin to ground to insure stability.

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 minimum

dropout voltage during the load transient response. This pin must always be 1.4V

(1.3V) higher than VOUT in order for the device to regulate properly.
