(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) All voltages are with respect to network ground terminal.
(3) While switching.

(1) The device is still functional down to under voltage lockout (see parameter VUVLO).
(2) Current into VIN pin.
(3) This is the static current limit. It can be temporarily higher in applications due to internal propagation delay (see Current Limit and Short Circuit Protection section).
(4) This is the voltage regulated at the FB pin.
(5) This is the accuracy provided by the device itself (line and load regulation effects are not included). For fixed voltage versions, the (internal) resistive feedback divider is included.
