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 or leave

floating. Do not connect to any potential other than the same ground potential seen at

device pin 5 (GND). See Power Dissipation for more information.
