39 / 151 page ![]() NXP Semiconductors FS2400 Fail-safe system basis chip with SMPS and LDO, CAN FD transceiver the MCU's responsibility to disable the regulator by SPI using V3DIS bit, and to decide when to enable it using V3EN bit. When a thermal shutdown is detected, the regulator is disabled and V3TSD_I flag is generated. 14.2.2 Application schematic aaa-046843 CIN_LDO3 COUT_LDO3 VLDO3 V3_IN V3 - HVLDO3 Figure 25. HVLDO3 application schematic 14.2.3 Electrical characteristics HVLDO3 electrical characteristics TA = –40 °C to 115 °C, unless otherwise specified. V3_IN = VSUP = 5.5 V to 40 V if V3 = 5 V, or V3_IN = VSUP = 4 V to 40 V if V3 = 3.3 V, unless otherwise specified. ILDO3 = 0 mA to 150 mA unless otherwise specified. All voltages referenced to ground.
