Notes
1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. For DIP24 packages: above 70 °C the value of Ptot derates linearly with 12 mW/K.
For SO24 packages: above 70 °C the value of Ptot derates linearly with 8 mW/K.
For SSOP24 and TSSOP24 packages: above 60 °C the value of Ptot derates linearly with 5.5 mW/K.
For DHVQFN24 packages: above 60 °C the value of Ptot derates linearly with 4.5 mW/K.
