connected to supply ground for proper device operation. For enhanced thermal, electrical, and board level

performance, the exposed pad needs to be soldered to the board using a corresponding thermal pad on the

board and for proper heat conduction through the board, thermal vias need to be incorporated in the

printed-circuit board in the thermal pad region.
