THERMAL SHUTDOWN
What do you think what is thermal shutdown?
Our electronic definitions web site has answer for that as well:

 


thermal shutdown

a feature found in modem threetertninal IC regulators. When the regulator exceeds a safe operating temperature, the pass transistor is cut off and the output voltage goes to zero. When the device cools, the pass transistor is again turned on. If the original cause of the excessive temperature is still present, the device again shuts off. If the cause has been removed, the device works normally. This feaure makes the regulator almost indestructible.


Another definition of thermal shutdown:
a feature found in modern three terminal IC regulators. When the regulator exceeds a safe operating temperature, the pass transistor is cut off and the output voltage goes to zero. When the device cools, the pass transistor is again turned on. IC the original cause of the excessive temperature is still present, the device again shuts off. If the cause has been removed, the device works normally. This feaure makes the regulator almost indestructible.
