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 (V
IN
- V
OUT
) when V
OUT
falls to 100mV below the value of V
OUT
measured when V

= V
OUT(NOM)
+0.5V.
Since the minimum input voltage is 2.7V, this specification is only meaningful when V
OUT
≥
2.7V.
Note 2:
The output voltage is externally set using a resistive voltage-divider from OUT to SET.
Note 3:
Specifications to -40°C are guaranteed by design, not production tested.
