Keywords:current limiter? linear regulator? supercap?

The LMP8646 is a precision current limiter employed to improve the current limit accuracy of any switching or linear regulator with an available feedback node. Many regulators might have an internal current limiter, but its output accuracy is often as high as 30%. The output accuracy of the LMP8646 can be as low as 3%, making it a preferred current limiter for many regulator applications. In this application note, we will discuss how to design the LMP8646 with the LM3102 voltage regulator and a supercap load application.
