TLE4251G

概要

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 given to the adjust input via an external resistor. The output is able to drive loads up to 400 mA while it follows e.g. the 5 V output of a main voltage regulator within an accuracy of 0.5%. For loads up to 300 mA, the tracking accuracy is 0.2%. The TLE 4251 can be switched in stand-by mode via the enable EN input which causes the current consumption to drop to very low values. This feature makes the IC suitable for low-power battery applications.
