THERMAL PROTECTION
the integrated circuit in the event that the maximum junction
temperature is exceeded. When activated, typically at
150°C, the output is disabled. There is no hysteresis built
into the thermal protection. As a result the output will appear
to be oscillating during thermal limit. The output will turn
off until the temperature drops below the 150°C then the
output turns on again. The process will repeat if the junction
increases above the threshold. This will continue until the
existing conditions allow the junction to operate below the
temperature threshold.

increasing the size of the output capacitor will reduce the
noise on the MC33375.
