[1] The minimum input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] For SO20 package: above 70 C the value of Ptot derates linearly with 8.0 mW/K.
For TSSOP20 package: above 60 C the value of Ptot derates linearly with 5.5 mW/K.
For DHVQFN20 package: above 60 C the value of Ptot derates linearly with 4.5 mW/K.
