... TDA1904 THERMAL SHUT-DOWN The presence of a thermal limiting circuit offers the following advantages overload on the output (even perma- nent above limit ambient temperature can be easily tolerated since the T higher than 150 C. 2) The heatsink can have a smaller factor of safety compared with that of a conventional circuit. ...
