THERMAL PROTECTION

Device operational range is limited by the maximum junction temperature (TJ). The junction temperature is

influenced by the ambient temperature (TA), package selection, input voltage (VIN), and the output load current.

When operating with maximum load currents the input voltage and/or ambient temperature will be limited. When

operating with maximum input voltage the load current and/or the ambient temperature will be limited.

Even though the LM9076 is equipped with circuitry to protect itself from excessive thermal dissipation, it is not

recommended that the LM9076 be operated at, or near, the maximum recommended die junction temperature

(TJ) as this may impair long term device reliability.

The thermal protection circuity monitors the temperature at the die level. When the die temperature exceeds

typically 160°C the voltage regulator output will be switched off.
