(1) This data is based on using the JEDEC High-K board, and the exposed die pad is connected to a copper pad on the board. This is connected

to the ground plane by a 2x3 via matrix.

(1) 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 or any other conditions beyond those indicated under “recommended operating

conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

† The IC continues to operate below Vmin, to 3.5 V, but the specifications are not tested nor guaranteed.

‡ The inherent switching noise voltage spikes should not exceed the absolute maximum rating on either the IN or OUT pins. A tight layout minimizes

switching noise.
