The TLE 4250 G is a monolithic integrated low-drop voltage tracker in the very small SMD package SCT 595. It is designed to supply e.g. sensors under the severe conditions of automotive applications. Therefore the device is equipped with additional protection functions against overload, short circuit and reverse polarity. Supply voltages up to 40 V are tracked to a reference voltage at the adjust input. Therefore the Adjust pin has to be connected to a reference voltage, e.g. to a 5 V supply on a micro-controller port.
