OUT

O

Output pin. A 2.2-

μF ceramic capacitor is connected from this pin to ground for stability and to provide load

transients; see the Input and Output Capacitor Requirements section.

I

Enable pin. A logic high signal on this pin turns the device on and regulates the voltage from IN to OUT.

A logic low on this pin turns the device off.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
