Overview

The RAR-iLR-qLR.01 Retention Alternating Regulator enables this combination embedding two regulation sub-components: a linear regulztor for logic (iLR) and an ultra low quiescent linear regulator (qLR). A Regulation Control Unit (RCU) manages booting and transitions between each regulation functions.

Key features

  • Ideal regulator for power and voltage islets
  • Secured integration in the SoC Embedded RCU (Regulator Control Unit) to manage booting and mode transitions and to ensure data integrity
  • Configurable output drive before delivery to fit the application
  • Performances in sleep mode: qLR with low quiescent current: 0.2 uA
  • Can supply always-on loads up to 300 μA
  • Accessible voltage reference can be used by wake-up circuitry
  • Low area compared to a combinaison with a switching regulator
  • Low Bill-of-Material: fully integrated feedback and active compensation loop to reduce the number of additional external passive components
  • Low Output Ripple
  • Over-temperature/Over-current protected Output
