The TO220 and TO263 TAB is a thermal and electrical connection
that is physically attached to the backside of the die, and used as
a thermal heat-sink connection. See the Application Information
section for details.
The PSOP DAP is a thermal connection only that is physically
attached to the backside of the die, and used as a thermal heat-
sink connection. See the Application Information section for details.
