Description

The TLE4250G 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 over load, short circuit and reverse polarity. At over temperature.

Supply voltages up to 40 V are tracked to a reference voltage at the adjust input. Therefore the Adjust/Enable pin has to be connected to the reference voltage via an external resistor controlled by an n-channel open drain or direct by a micro-controller port.

The TLE4250G output is able to drive a load up to 50 mA while it follows e.g. the 5 V output of a main voltage regulator within an accuracy of 0.5%.

The TLE4250G can be switched in stand-by mode via the adjust/enable input which causes the current consumption to drop to very low values. This feature makes the IC suitable for low power battery applications.
