it will cause the over temperature protection.

Over-Temperature Protection

The recommended operating junction temperature range is –40°C to 125°C. When the junction temperature is between 125°C and

the thermal shutdown (TSD) threshold, the regulator can still work well, but will reduce the device lifetime for long-term using.

The over-temperature protection works when the junction temperature exceeds the thermal shutdown (TSD) threshold, which turns

off the regulator immediately. Until when the device cools down and the junction temperature falls below the thermal shutdown

threshold minus thermal shutdown hysteresis, the regulator turns on again.
