Linear IC regulators contain built-in protection circuits which make them virtually immune to damage from either excessive load current or high operating temperature.
A rise in die temperature (regardless of cause) approaching the limit threshold (about 160°C) will cause the thermal shutdown to cut drive to the power transistor, thereby reducing load current and internal power dissipation. Note that the thermal limiter can override both the current limit circuits and the voltage error amplifier. Thermal shutdown is detailed in the next section.
