The IC is available in a PG-DSO-14-30 package. It is designed to supply microprocessor systems under the severe conditions of automotive applications and therefore equipped with additional protection functions against overload, short circuit and overtemperature. The TLE 4278 can also be used in other applications where a stabilized voltage is required. An input voltage VI in the range of 5.5 V ≤ VI ≤ 45 V is regulated to VQ,nom = 5 V with an accuracy of ±2%. The device operates in the wide temperature range of Tj = -40 to 150 °C. Two additional features are implemented in the TLE 4278 a load dependent watchdog function as well as a sophisticated reset function including power on reset, under voltage reset, adjustable reset delay time and adjustable reset switching threshold.
