T A(max) = maximum ambient operating temperature
For example, the maximum ambient temperature is 50°C,
the ΔT is determined as follows:
ΔT = 125°C – 50°C
ΔT = 75°C
Using Figure 4, the minimum amount of required copper can
be determined based on the required power dissipation. Power
dissipation in a linear regulator is calculated as follows:
P D = (V IN – V OUT ) I OUT + V IN × I GND
If we use a 2.5V output device and a 3.3V input at an output
current of 750mA, then our power dissipation is as follows:
P D = (3.3V – 2.5V) × 750mA + 3.3V × 7.5mA
P D = 600mW + 25mW
P D = 625mW
From Figure 4, the minimum amount of copper required to
operate this application at a ΔT of 75°C is 160mm 2 .
Quick Method
Determine the power dissipation requirements for the design
along with the maximum ambient temperature at which the
device will be operated. Refer to Figure 5, which shows safe
Micrel
operating curves for three different ambient temperatures:
25°C, 50°C and 85°C. From these curves, the minimum
amount of copper can be determined by knowing the maxi-
mum power dissipation required. If the maximum ambient
temperature is 50°C and the power dissipation is as above,
625mW, the curve in Figure 5 shows that the required area
of copper is 160mm 2 .
The θ JA of this package is ideally 80°C/W, but it will vary
depending upon the availability of copper ground plane to
which it is attached.
