Notes
1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. For SO14 packages: above 70 °C derate linearly with 8 mW/K.
For SSOP14 and TSSOP14 packages: above 60 °C derate linearly with 5.5 mW/K.
For DHVQFN14 packages: above 60 °C derate linearly with 4.5 mW/K.
For DIP14 packages: above 70 °C derate linearly with 12 mW/K.
