The L4923 is a Heptawat high-current monolithic voltage regulator with very low voltage drop (0.70 V max at 1 A, TJ = 25 °C). The device is internally protected against load dumps transient of + 60 V, input overvoltage, reverse polarity, overheating and output short circuit: thanks to these features the L4923 is very suited for automotive and industrial applications. The reset function is very useful for power off and power on information when supplying a microprocessor. The inhibit function reduces drastically the consumption when no load current is required: typically the standby current value is 300 µA.
