RAR-eSR-qLR-ref-1.62-3.63-0.55-2.5.04_TSMC_40_uLPeF is a Retention Alternating Regulator in TSMC 40uLPeF combining 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
- Single input voltage supporting 1.62 V to 3.63 V
- Junction temperature range from -40°C to 125°C
- Manages booting and transitions between embedded regulators
- Enables high power and low power operating modes
- Embedded power pads with ESD protection
- Designed with standard IO transistors (2.5 V od 3.3 V) and SVT core transistors
- Compliant with Maestro, Dolphin's power controller
- Integrated Local Supply Monitoring (LSM)
- Selectable source of clock (internal or external)
