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
