(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) The accuracy in Power Save Mode can be improved by increasing the COUT value, reducing the output voltage ripple.
(5) Line and load regulation are depending on external component selection and layout (see Figure 14 and Figure 15).
