[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] For DIP20 packages: above 70 °C the value of Ptot derates linearly with 12 mW/K.
For SO20 packages: above 70 °C the value of Ptot derates linearly with 8 mW/K.
For (T)SSOP20 packages: above 60 °C the value of Ptot derates linearly with 5.5 mW/K.
