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 T
A
(ambient temperature) is calculated using: P
D(MAX)
=
(T

– T
A
)/
Θ
JA
. 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.
