Thermal Information
Thermal Protection
Thermal protection disables the output when the
junction temperature rises to approximately +165
°
C,
allowing the device to cool. When the junction
temperature cools to approximately +145
°
C the
output circuitry is again enabled. Depending on power
dissipation,
thermal
resistance,
temperature, the thermal protection circuit may cycle
on and off. This cycling limits the dissipation of the
regulator,
protecting
it
overheating.
Power Dissipation
The ability to remove heat from the die is different for
each
package
type,
considerations in the PCB layout. The PCB area
around the device that is free of other components
moves the head from the device to the ambient air.
Performance data for JEDEC low- and high-K boards
are given in the
Dissipation Ratings
table. Using
heavier copper will increase the effectiveness in
removing heat from the device. The addition of plated
through-holes to heat-dissipating layers will also
improve the heatsink effectiveness.
