IN

8

The input of the regulator. Bypass to ground through at least 1µF ceramic

capacitor.

OUT

1

The output of the regulator. Bypass to ground through at least 2.2µF ceramic

capacitor. For improved ac load response a larger capacitor is recommended.

GND

4

Ground.

ADJ

3

Adjustable voltage version only – a resistor divider from this pin to the OUT pin

and ground sets the output voltage.

EN
