LM2831 Overview
The LM2831 regulator is a monolithic, highfrequency, PWM step-down DC-DC converter in a 5pin SOT-23 and a 6-Pin WSON package. The LM2831 provides all the active functions to provide local DC-DC conversion with fast transient response and accurate regulation in the smallest possible PCB area. With a minimum of external ponents, the LM2831 is easy to use.
