[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] When VCC = 0 V (power-down mode), the output voltage can be 3.6 V in normal operation.
[3] For SO20 packages: above 70 °C derate linearly with 8 mW/K.
For 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.
