An external bypass capacitor connected to this pin, in conjunction with an internal

resistor, creates a low-pass filter to further reduce regulator noise.

I

The EN pin is an input which enables or shuts down the device. The enable signal

is an active-low digital control that enables the device, so when EN is a logic high

(> 2 V), the device is in shutdown mode. When EN is logic low (< 0.7 V), the

device is enabled.

The OUT pin is the regulated output of the device.

(1)

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.

(2)

All voltage values are with respect to the network ground pin.
