RAR-iLR-qLR-1.62-3.63-0.55-2.5.01_TSMC_55_uLPeF is a Retention Alternating Regulator in TSMC 55uLPeF combining two regulation sub-components: a linear regulator 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 Benefits
- 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
