NOTE: The XRT73L03 is assembled in a thermally
enhanced package with an intergral Copper Heat Slug.
The Heat Slug is solder plated and is exposed on the bot-
tom of the package and is electrically connected to the
Ground connections of the device. This Heat Slug can be
soldered to the mounting board if desired, but must be iso-
lated from any VDD connections.
