Power Management Unit (PMU)
5.3.2 Voltage Regulator 1.5V (VDDC)
This module represents the 1.5 V voltage regulator, which provides the supply for the microcontroller core, the
digital peripherals and other internal analog 1.5 V functions (e.g. ADC2) of the chip. To further reduce the current
consumption of the MCU during Stop Mode the output voltage can be lowered to 0.9 V.
Features
• 1.5 V low-drop voltage regulator
• Overcurrent monitoring and shutdown with MCU signaling (interrupt)
• Overvoltage monitoring with MCU signaling (interrupt)
• Undervoltage monitoring with MCU signaling (interrupt)
• Undervoltage monitoring with reset
• Pull Down Current Source at the output for Sleep Mode only (typ. 100 μA)
The output capacitor C_VDDC is mandatory to ensure a proper regulator functionality.
