(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).

(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.
