Power Management Unit (PMU)
5.3.3 External Voltage Regulator 5.0V (VDDEXT)
This module represents the 5 V voltage regulator, which serves as a supply for external circuits. It can be used
e.g. to supply an external sensor, LEDs or potentiometers.
Features
⢠Switchable +5 V, low-drop voltage regulator
⢠Switch-on overcurrent blanking time in order to drive small capacitive loads
⢠Overcurrent monitoring and shutdown with MCU signaling (interrupt)
⢠Overvoltage monitoring with MCU signaling (interrupt)
⢠Undervoltage monitoring with MCU signaling (interrupt)
⢠Pull Down current source at the output for Sleep Mode only (typ. 100 μA)
⢠Cyclic sense option together with GPIOs
The output capacitor CVDDEXT is mandatory to ensure a proper regulator functionality.
