[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] For TSSOP8 package: above 55 °C the value of Ptot derates linearly at 2.5 mW/K.
For VSSOP8 package: above 110 °C the value of Ptot derates linearly at 8 mW/K.
For XSON8U packages: above 118 °C the value of Ptot derates linearly with 7.8 mW/K.
