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

[2] VCCO is the supply voltage associated with the output port.

[3] VCCO + 0.5 V should not exceed 4.6 V.

[4] For SO16 package: above 70 C the value of Ptot derates linearly at 8 mW/K.

For TSSOP16 package: above 60 C the value of Ptot derates linearly at 5.5 mW/K.

For DHVQFN16 package: above 60 C the value of Ptot derates linearly at 4.5 mW/K.

[5] For XQFN16 package: above 133 C the value of Ptot derates linearly with 14.5 mW/K.
