[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] For SOT108-1 (SO14) package: Ptot derates linearly with 10.1 mW/K above 100 °C.
For SOT402-1 (TSSOP14) package: Ptot derates linearly with 7.3 mW/K above 81 °C.
For SOT762-1 (DHVQFN14) package: Ptot derates linearly with 9.6 mW/K above 98 °C.
