Limiting values [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 P tot derates linearly at 2.5 mW/K. For VSSOP8 package: above 110 °C the value of P tot derates linearly at 8 mW/K. For XSON8U packages: above 118 °C the value of P tot derates linearly with 7.8 mW/K. 10. Recommended operating conditions 11. Static characteristics Table 5.
