Notes:

Exceeding maximum ratings may damage the device.

The device is not guaranteed to work outside its operating ratings.

The maximum allowable power dissipation of any T

A (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.
