This device an automotive suited voltage regulator with a fixed 5-V output. The maximum operating voltage is 45 V. The output is able to drive 150 mA load. It is short circuit protected and the thermal shutdown switches the output off if the junction temperature is in excess of 150 ° C. A reset signal is generated for an output voltage of V Q < 4.65 V. The reset threshold voltage can be decreased by external connection of a voltage divider. The reset delay time can be set by an external capacitor. Reset and sense output have integrated pull-up resistors. If the integrated resistors are not desired TLE 4279 can be used. It is also possible to supervise the input voltage by using an integrated comparator to give a low voltage warning.
