Exceeding an absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
The maximum allowable power dissipation at any T
dissipation results in excessive die temperature, and causes the regulator to enter thermal shutdown.
Devices are ESD sensitive; use proper handling precautions.
