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. Summary of Features Output tracking tolerance ≤ ±0.2% 400 mA output current capability Enable Function Very low current consumption in OFF mode Wide operation range: up to 40 V Wide temperature range: -40 °C ≤ T j ≤ 150 °C Output protected against short circuit Overtemperature protection Reverse polarity proof Green Product (RoHS compliant) AEC Qualified Benefits Efficient and accurate voltage replication Heat distribution in the system Robust tracking supply Potential Applications Sensor Supply Heat distribution Secondary µcontroller supply Family Overview For an overview of other available options in this family please click here.
