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:
Dropout voltage is defined as V
IN
- V
OUT
, when V
OUT
is 100mV below the value of V
OUT
measured when V
IN
= V
OUT(NOM)
+ 0.5V. Since the minimum input voltage is 2.5V, this specification is only meaningful when V
OUT(NOM)
≥
2.5V. For V
OUT(NOM)
between 2.5V and 3.5V, use the following equations: Typical Dropout = -93mV/V
V
OUT(NOM)
+ 445mV; Guaranteed Maximum
Dropout = -137mV/V
V
OUT(NOM)
+ 704mV. For V
OUT(NOM)
≥
3.5V: Typical Dropout = 120mV; Guaranteed Maximum Dropout
= 225mV.
Note 2:
Specifications to -40°C are guaranteed by design, not production tested.
