[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 the value of Ptot derates linearly with 8 mW/K.
For (T)SSOP20 packages: above 60 C the value of Ptot derates linearly with 5.5 mW/K.
For DHVQFN20 packages: above 60 C the value of Ptot derates linearly with 4.5 mW/K.
