Thermal PAD
Function
Power Output Pin
Ground
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
Power Input Pin
In PCB layout, it is preferred 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

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 is a 2in. x 2in. multi-layer board
with 1oz. internal power and ground planes and 2oz. copper traces on the top and bottom of the board.
