(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress

ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under

Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device

reliability.

(1)

All capacitor values are assumed to derate to 50% of the nominal capacitor value. Maintain an effective output capacitance of 1 μF

minimum for stability.

(2)

Minimum input capacitor of 2.2 μF is recquired if the source impedance is more than 0.5 Ω.
