Note 1: Exceeding the absolute maximum rating may damage the device.

Note 2: The device is not guaranteed to function outside its operating rating.

Note 3: The maximum allowable power dissipation at any TA (ambient temperature) is calculated using: 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. See “Thermal Consideration” section for details

Note 4: RESET threshold temperature coefficient is the worst case voltage change divided by the total temperature

range.
