(1) The device is still functional down to Undervoltage Lockout (see parameter VUVLO).
(2) Current into AVIN + PVIN 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).
(4) This is the accuracy provided at the FB pin (line and load regulation effects are not included).
(5) Line and load regulation depend on external component selection and layout (see Figure 20 and Figure 21).
