PIN FUNCTIONS

Pin N

° Name

Function

1

IN

Unregulated input voltage; this pin must be bypassed with a capacitor larger than 10

µF.

2

GND

To connect to Ground to get 1.5V, 1.8V, 2.5V or 3.3V output.

3

OUT

Regulated output voltage. A minimum bypass capacitor of 22

µF is required to insure stability.
