The TLE4295G is a monolithic integrated low-drop voltage regulator in the very smallSMD package SCT-595. It is designed to supply e.g. microprocessor systems under thesevere conditions of automotive applications. Therefore the TLE4295 is equipped withadditional protection functions against over load, short circuit and reverse polarity. Atovertemperature the regulator is automatically turned off by the integrated thermal protection circuit.
Input voltages up to 40V are regulated to V = 3.0V (V30 version) 3.3V (V33 Q,nom version) or 5.0 V (V50 version). The output of TLE4295 is able to drive a load of more than 30 mA while it regulates the output voltage within a 4% accuracy. The power fail output (open collector) is switched to low in case of undervoltage overload or saturation of the output transistor.
