[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] For DIP16 package: Ptot derates linearly with 12 mW/K above 70 °C.
[3] For SO16 package: Ptot derates linearly with 8 mW/K above 70 °C.
[4] For SSOP16 and TSSOP16 packages: Ptot derates linearly with 5.5 mW/K above 60 °C.
[5] For DHVQFN16 package: Ptot derates linearly with 4.5 mW/K above 60 °C.
