[1] The minimum input voltage ratings may be exceeded if the input current ratings are observed.

[2] The output voltage ratings may be exceeded if the output current ratings are observed.

[3] For SO20 packages: above 70 C derate linearly with 8 mW/K.

For (T)SSOP20 packages: above 60 C derate linearly with 5.5 mW/K.

For DHVQFN20 packages: above 60 C derate linearly with 4.5 mW/K.
