Exposed pad

Thermal Pad

—

The exposed thermal pad on the bottom of the package must be connected to a copper area

under the package on the PCB. Connect to ground potential. Do not connect to any potential

other than the same ground potential seen at device pins 4 and 8 (GND). See Power

Dissipation for more information.
