[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] For DIP14 package: P_tot derates linearly with 12 mW/K above 70 C.
[3] For SO14 package: P_tot derates linearly with 8 mW/K above 70 C.
For (T)SSOP14 packages: P_tot derates linearly with 5.5 mW/K above 60 C.
