(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under
Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device
reliability.
(2) A voltage of 2 V below GND and 2 V above VIN can appear on this pin for ≤200 ns with a duty cycle of ≤0.01%.
(3) This specification applies to voltage durations of 100 ns or less. The maximum D.C. voltage should not exceed ± 0.3 V.
(4) Do not exceed pin’s voltage rating.

(1) Recommended operating conditions indicate conditions for which the device is intended to be functional, but do not ensure specific
performance limits. For ensured specifications, see Electrical Characteristics table.
(2) Under no conditions should the output voltage be allowed to fall below zero volts.
(3) Maximum continuous DC current may be derated when operating with high switching frequency and/or high ambient temperature. See
Application section for details.
