(3)
-40°C to 85°C
(3) The maximum ambient temperature (T
A(max)
) is dependant on the maximum operating junction temperature (T
J(max-op)
= 125°C), the
maximum power dissipation of the device in the application (P
D(max)
), and the junction to ambient thermal resistance of the part/package
in the application (θ
JA
), as given by the following equation: T
A(max)
= T
J(max-op)
- (θ
JA
× P

).

(1) Absolute Maximum Ratings are limits beyond which damage can occur. Operating Ratings are conditions under which operation of the
device is ensured. Operating Ratings do not imply ensured performance limits. For ensured performance limits and associated test
conditions, see the Electrical Characteristics tables.
(2) Junction to ambient thermal resistance is dependant on the application and board layout. In applications where high maximum power
dissipation is possible, special care must be paid to thermal dissipation issues in board design.

(1) All Voltages are with respect to the potential at the GND pin.
(2) Min Max limits are ensured by design, test or statistical analysis. Typical numbers are not ensured, but do represent the most likely
norm.

(4) Dropout voltage is voltage difference between input and output at which the output voltage drops to 100mV below its nominal value.
This parameter only for output voltages above 2.0V
