1.5A Ultra Low Dropout Positive Adjustable or Fixed-mode Regulator
Functional Descriptions (Continued)
Thermal Design
The AP1186-XXX incorporates an internal thermal
shutdown that protects the device when the junction
temperature exceeds the allowable maximum
junction temperature. Although this device can
operate with junction temperatures in the range of
150
C, it is recommended that the selected heat
sink be chosen such that during maximum
continuous load operation the junction temperature
is kept below this number. The example below
shows the steps in selecting the proper surface
mount package.

Copper Area
TO263
Pad Size-1.4”X1.4”
Note:
Above table is based on the maximum junction temperature of 135
o
C.
As shown in the above table, any of the two packages will do the job.

Assuming, the following conditions:
Vout=2.5V
Vin=3.3V
Vctrl=5V
Iout=1.5A DC Avg.
Calculate the maximum power dissipation using
the following equation:
Pd=Iout*(Vin-Vout)+(Iout/60)*(Vctrl-Vout)
Pd=2*(3.3-2.5)+(2/60)*(5-2.5)=1.68W
Using table below select the proper package
and the amount of copper board needed.
