Combo voltage regulator designed in TSMC 40 ULP eFlash, 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
