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