Combo voltage regulator designed in TSMC 22ULL, combining a linear regulator for active mode with an ultra-low quiescent regulator for low-power operation in sleep mode. A Regulation Control Unit (RCU) manages booting and safe transitions between each regulation functions to ease SoC integration.
Key Benefits
- Embedded RCU (Regulator Control Unit) to manage booting and safe mode transitions
- Configurable LDO output current to fit the application (from 100 mA to 500 mA)
- Low Bill-of-Material: fully integrated feedback and active compensation loop to reduce the number of additional external passive components
- Low Output Ripple
- Low quiescent current for AON supply with stringent power consumption constraints in sleep mode
