ADP1712/ADP1713/ADP1714
THERMAL CONSIDERATIONS
To guarantee reliable operation, the junction temperature of the
ADP1712/ADP1713/ADP1714 must not exceed 125°C. To
ensure the junction temperature stays below this maximum value,
the user needs to be aware of the parameters that contribute to
junction temperature changes. These parameters include ambient
temperature, power dissipation in the power device, and thermal
resistances between the junction and ambient air (θ JA ). The θ JA
number is dependent on the package assembly compounds used
and the amount of copper to which the GND pin of the package

MAX T J (DO NOT OPERATE ABOVE THIS POINT)
The junction temperature of the ADP1712/ADP1713/ADP1714
can be calculated from the following equation:
60
T J = T A + ( P D × θ JA )
where:

V IN and V OUT are input voltage and output voltage, respectively.
Power dissipation due to ground current is quite small and can
be ignored. Therefore, the junction temperature equation
simplifies to the following:

T J = T A + {[( V IN – V OUT ) × I LOAD ] × θ JA }
