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.
The junction to ambient thermal resistance
θ
rating has
two distinct components: the junction to case thermal resis-
tance rating
θ
JC
; and the case to ambient thermal resistance
rating
θ
CA
. The relationship is defined as:
θ
JA
=
θ
JC
+
θ
CA
.
For the SO-8 and TO-252 surface mount packages the
θ
JA
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.
