[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] For SO14 packages: above 70 °C the value of Ptot derates linearly at 8 mW/K.
For TSSOP14 packages: above 60 °C the value of Ptot derates linearly at 5.5 mW/K.
For DHVQFN14 packages: above 60 °C the value of Ptot derates linearly at 4.5 mW/K.
