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

[2] For SO16 packages: above 70 °C the value of Ptot derates linearly at 8 mW/K.

For (T)SSOP16 packages: above 60 °C the value of Ptot derates linearly at 5.5 mW/K.

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