A4402 Overview
The A4402 is a dual-output regulator, bining in a single package a constant on-time buck regulator and a linear regulator (LDO) each with adjustable output voltages. It is ideal for applications that require two regulated voltages, such as in microcontroller- or DSP-based applications requiring core and I/O voltage rails. The buck regulator output supplies the adjustable linear regulator to reduce power dissipation...
