| Low Drop Voltage Regulator TLE 4295 Features * * * * * * * * * * * * * * Four versions: 2.6 V, 3.0 V, 3.3 V, 5.0 V Output voltage tolerance 4% Very low drop voltage Output current: 30 mA Power fail output Low quiescent current consumption Wide operation range: up to 45 V Wide temperature range: -40 C Tj 150 C Output protected against short circuit Overtemperature protection Reverse polarity proof Very small SMD-Package PG-SCT595-5 Green Product (RoHS compliant) AEC Qualified PG-SCT595-5 Functional Description The TLE 4295 G is a monolithic integrated low-drop voltage regulator in the very small SMD package PG-SCT595-5. 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 = 2.6 V (V26 version) 3.0 V (V30 version) 3.3 V (V33 version) or 5.0 V (V50 version). The output 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.
