It is designed to supply e.g. microprocessor systems under the severe conditions of automotive applications. Therefore, the device is equipped with additional protection functions against overload, short circuit and reverse polarity. At overtemperature the regulator is automatically turned off by the integrated thermal protection circuit. Input voltages up to 40 V are regulated to VQ,nom = 5.0 V. The output is able to drive a load of more than 30 mA, while it regulates the output voltage within a 4% accuracy.
