(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 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 the fixed voltage versions the

(internal) resistive divider is included.

(6)

Line and load regulation depend on external component selection and layout (see Figure 17 and Figure 18).
