Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Note 1:
Devices are 100% production tested at T
A
= +25°C and are guaranteed by design from T
A
= T
MIN
to T
MAX
.
Note 2:
Not production tested. Guaranteed by design.
Note 3:
Dropout voltage is the minimum input voltage at which V
OUT
changes ≤ 0.2% from V
OUT
at rated V
IN
and is guaranteed by
Load Regulation Test.
Note 4:
Thermal hysteresis is defined as the change in T
A
= +25°C output voltage before and after temperature cycling of the device
(from T
A
= T
MIN
to T
MAX
). Initial measurement at T
A
= +25°C is followed by temperature cycling the device to T
A
= +85°C
then to T
A
= -40°C and another measurement at T
A
= +25°C is compared to the original measurement at T
