Typical Performance Characteristics
Applications Information
Unlike other PNP low dropout regulators, the LM2936 re-
mains fully operational to 40V. Owing to power dissipation
characteristics of the available packages, full output current
cannot be guaranteed for all combinations of ambient tem-
perature and input voltage.

For the SO-8 and TO-252 surface mount packages the θ
rating can be improved by using the copper mounting pads
on the printed circuit board as a thermal conductive path to
extract heat from the package.
