5.2 Pin description

[1]

pin must be 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 PCB in the thermal pad region.
