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

Overview

Key Features

• 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
• Performances in sleep mode: qLR with low quiescent current: 0.2 µA
• Can supply always-on loads up to 300 μA
• Accessible voltage reference can be used by wake-up circuitry
• Performances in normal mode: PFM embedded mode allowing high-efficiency at low load
• High Efficiency (up to 95% peak efficiency)
• 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
