Overview

The RAR-eSR-qLR Retention Alternating Regulator combines two regulation sub-components: a high-efficiency switching regulator (eSR) and an ultra low quiescent linear regulator (qLR). A Regulation Control Unit (RCU) manages booting and transitions between each regulation functions.

Key features

  • Perfect fit for battery-powered IoT applications that require both high-efficiency during active mode and ultra-low power consumption in AON domain during sleep and deep sleep mode
  • Support of input voltage from 1.9V to 5.5V (Li-Ion, USB supplies)
  • Embedded RCU (Regulator Control Unit) to manage booting and mode transitions and to ensure data integrity
  • Configurable output current to fit the application

How to simplify switch-mode DC-DC converter design

This article focuses on the design issues that are simplified by including an integrated inductor optimized for a range of electrical and layout applications as part of the power management solution

Breaking new energy efficiency records with advanced power management platform

The free lunch offered for decades by Moore’s law is now over and scaling down to the next technology node no longer offers the required energy efficiency gains. Design teams must now pursue their gains by deploying increasingly complex power management techniques to meet the demands of the new IoT markets.

Guide to Choosing the Best LDO for Your Application

To know which LDO you need, you must first define the application of your LDO and then examine which parameters are most important when dealing with that application. With the multiple parameters that characterize a particular LDO, it is not easy to determine which LDO is best suited. To help you figure this out, we have put together this reference. This guide presents a list of all the key LDO parameters along with their definitions, the most common applications of LDOs, and which parameters are critical for each.
