5.3.1 Voltage Regulator 5.0V (VDDP)
This module represents the 5 V voltage regulator, which provides the pad supply for the parallel port pins and other
5 V analog functions (e.g. LIN Transceiver).
Features
• 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 (Undervoltage Reset, V_DDPUV)
• Pre-Regulator for VDDC Regulator
• GPIO Supply
• Pull Down Current Source at the output for Sleep Mode only (typ. 5 mA)
The output capacitor C_VDDP is mandatory to ensure proper regulator functionality.
