Copper area lay out information

Determine the power dissipation requirements for the design along with the maximum ambient temperature at which

the device will be operated. Refer to power dissipation with copper area curve, which shows safe operating curves for

three different ambient temperatures with 25

be determined by knowing the maximum power dissipation required.

If we used a 5.0V output device and a 6V input at an output current of 350mA, then the power dissipation is as follows:

If the maximum ambient temperature is 85

the required area of copper is 80mm
