The input negative voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
This value is limited to 3.6V maximum.
The package thermal impedance is calculated in accordance with JESD 51.
Stresses greater than those listed under MAXIMUM RAT INGS may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above those in di cat ed in the operational sec tions of this spec i fi ca tion is not
im plied. Exposure to absolute maximum rating conditions for ex tend ed periods may affect reliability.
