[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] For SO20 packages: above 70 C the value of Ptot derates linearly at 8 mW/K.
For TSSOP20 packages: above 60 C the value of Ptot derates linearly at 5.5 mW/K.
For DHVQFN20 packages: above 60 C the value of Ptot derates linearly at 4.5 mW/K.
