Notes:

Exceeding the absolute maximum rating may damage the device.

The device is not guaranteed to function outside its operating rating.

The maximum allowable power dissipation of any TA (ambient temperature) is PD(max) = (TJ(max) – TA) / θJA. Exceeding the maximum allowable power

dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.

Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5kΩ in series with 100pF.
