Product: RAR-eSR-qLR-ref-[1.62-3.63]-[0.55-2.5].04 TSMC 40 nm

Retention Alternative Regulator, combines high efficiency in normal mode and ultra-low quiescent current for sleep mode, DELTA standard

 

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 Benefits

    • Ideal regulator for power and voltage islets
    • 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
    • High Efficiency (up to 95% peak efficiency)
