To Diode Anode. Connected to remote discrete
diode junction or to the diode junction on a remote
IC whose die temperature is being sensed. When
not used they should be left floating.
To Diode Cathode. Must float when not used.

Left floating. PC board traces may be routed
through the pads for these pins, although the
components that drive these traces should share
the same supply as the LM82 so that the Absolute
Maximum Rating, Voltage at Any Pin, is not
violated.
