[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] All supply and ground pins connected externally to one voltage source.
[4] Above 70 C the value of Ptot derates linearly with 1.8 mW/K.
