Note: NOT to Scale
The above drawing is a representation of how the heat can be conducted away from the die using an exposed pad package. Each
application will have different requirements and limitations and therefore the user should use sufficient copper to dissipate the
power in the system. The output current rating for the linear regulators may have to be de-rated for ambient temperatures above
85C. The de-rate value will depend on calculated worst case power dissipation and the thermal management implementation in
the application.
Application Using A Single Layer PCB
Use as much Copper Area
as possible for heat spread
Package Thermal Pad
Package Outline
Layout recommendations for a Single Layer PCB: utilize as much Copper Area for Power Management. In a single layer board
application the thermal pad is attached to a heat spreader (copper areas) by using low thermal impedance attachment method
(solder paste or thermal conductive epoxy).
In both of the methods mentioned above it is advisable to use as much copper traces as possible to dissipate the heat.
IMPORTANT:
If the attachment method is NOT implemented correctly, the functionality of the product is not guaranteed. Power dissipation
capability will be adversely affected if the device is incorrectly mounted onto the circuit board.
