LC2251 Overview
The LC2251 is a high-efficiency, DC-to-DC stepdown switching regulators, capable of delivering up to 1.5A of output current. The device operates from an input voltage range of 2.6V to 5.5V and provides an output voltage from 0.6V to VIN. Working at a fixed frequency of 2MHz allows the use of small external ponents, such as ceramic input and output caps, as well as small inductors, while still providing low output...
