Enable pin. This pin should be driven either high or low and must not be floating. Driving this pin

high enables the regulator, while pulling it low puts the regulator into shutdown mode

4

Power Input pin

Thermal PAD

In PCB layout, prefer to use large copper area to cover this pad for better thermal dissipation, then

connect this area to GND or leave it open. However do not use it as GND electrode function alone.

Note:

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

functional operation of the device at these conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may

affect device reliability.

b). Ratings apply to ambient temperature at 25°C . The JEDEC High-K board design used to derive this data was a 2 inch x 2 inch multilayer board

with 1-ounce internal power and ground planes and 2-ounce copper traces on the top and bottom of the board.
