Functional Features
• 5 V low-drop voltage regulator
• Protected against short to battery voltage, e.g. for off-board sensor supply
• Can also be used for CAN supply
• VCC2 under voltage monitoring. Please refer to Chapter 13.8 for more information
• Can be active in SBC Normal, SBC Stop, and SBC Sleep Mode (not SBC Fail-Safe Mode)
• VCC2 switch off after entering SBC Restart Mode. Switch off is latched, LDO must be enabled via SPI after
shutdown.
• Over temperature protection
• ≥ 470nF ceramic capacitor at output voltage for stability, with ESR < 1Ω @ f = 10 kHz, to achieve the voltage
regulator control loop stability based on the safe phase margin (bode diagram).
• Output current capability up to I_VCC2,lim.
