... Thermal shutdown circuit The S-1142 Series has a thermal shutdown circuit to protect the device from damage due to overheat. When the junction temperature rises to 150°C (Typ.), the thermal shutdown circuit operates to stop regulating. When the junction temperature drops to 125°C (Typ.), the thermal shutdown circuit is released to restart regulating. ...
