Voltage regulator with backup and reset, overvoltage protection and low voltage warning

L4954 is a quad output voltage regulator and a three output high side driver.\n The IC includes monitoring circuitry to warn the microprocessor of a low voltage condition: the LVWarn, output, sensing the slow dropping of STCAP pins voltage, gives the microprocessor time to store data.\n A • 4 regulators:\n• 10 V (40 mA) low dropout\n• 8.5 V (175 mA)\n• 5 V (650 mA)\n• 5 V (100 mA) standby\n• 3 high side drivers:\n• 2 A (HSD1)\n• 0.3 A (HSD2 & HSD3)\n• No external charge pump capacitors are required\n• Standby mode controlled by 3 input pins:\n• EN1 for REG1, REG2, REG3 and HSD1\n• EN;
