THERMAL SHUT-DOWN
The presence of a thermal limiting circuit offers the
following advantages:
1) An overload on the output (even if it is perma-
nent), or an above limit ambient temperature
can be easily supported since the Tj cannot be
higher than 150
°C.
2) The heatskink can have a smaller factor of
safety compared with that of a conventional

MOUNTING INSTRUCTIONS
The power dissipated in the circuit must be re-
moved by adding an external heatsink.
Thanks to the Multiwatt package attaching the
heatsink is very simple, a screw or a compression

circuit. There is no possibility of device damage
due to high junction temperature.
If for any reason, the junction temperature in-
creases up to 150
°C, the thermal shut-down
simply reduces the power dissipation and the
current consumption.
The maximum allowable power dissipation de-
pends upon the size of the external heatsink (i.e. its
thermal resistance); fig. 31 shows this dissipable
power as a function of ambient temperature for
different thermal resistance.
spring (clip) being sufficient. Between the heatsink
and the package it is better to insert a layer of silicon
grease, to optimize the thermal contact; no electri-
cal isolation is needed between the two surfaces.
