THERMAL INFORMATION
THERMAL PROTECTION
Thermal protection disables the output when the
junction temperature rises to approximately +160°C,
The internal protection circuitry of the TPS780 series
has been designed to protect against overload
conditions. However, it is not intended to replace

on and off again. This cycling limits the dissipation of
the regulator, protecting it from damage as a result of
overheating.

The ability to remove heat from the die is different for
each package type, presenting different
considerations in the PCB layout. The PCB area
around the device that is free of other components
