Notes

1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

2. For SO20 packages: above 70 °C derate linearly with 8 mW/K.

For SSOP20 and TSSOP20 packages: above 60 °C derate linearly with 5.5 mW/K.

For DHVQFN20 packages: above 60 °C derate linearly with 4.5 mW/K.
