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

[2] VCCO is the supply voltage associated with the output.

[3] For SOT137-1 (SO24) package: Ptot derates linearly with 16.2 mW/K above 119 °C.

For SOT355-1 (TSSOP24) package: Ptot derates linearly with 12.4 mW/K above 110 °C.

For SOT815-1 (DHVQFN24) package: Ptot derates linearly with 15.0 mW/K above 117 °C.
