(1)

Condition does not apply to input voltages below 2.5 V because this is the minimum input operating voltage.

(2)

All limits are verified by testing or statistical analysis.

(3)

Typical values represent the most likely parametric norm.

(4)

does not apply to the 1.8-V version.

(5)

The SET pin is not externally connected for the fixed versions.
