Voltage Regulator 1.5V (VDDC)
This module represents the 1.5 V voltage regulator, which provides the supply for the microcontroller core,
digital peripherals and other chip internal analog 1.5 V functions (e.g. ADC).
Features
• 1.5 V low-drop voltage regulator
• Overcurrent monitoring and Shutdown with MCU signalling (Interrupt)
• Overvoltage monitoring with MCU signalling (Interrupt)
• Undervoltage monitoring with MCU signalling (interrupt)
• Undervoltage monitoring with reset
• Overtemperature Shutdown with MCU signalling (Interrupt)
• Pull Down Current Source at the output for Sleep Mode only (typ. 100
μ
A)
The output capacitor
