Low Dropout Tracking Regulator TLE 4252 G Features Output tracking tolerance to reference 0.2% Output voltage adjust down to 1.5 V 250 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 150 C j Output protected against short circuit to GND and Battery Overtemperature protection Reverse polarity proof Green Product (RoHS compliant) AEC Qualified Short Functional Description The TLE 4252 is a monolithic integrated low-dropout voltage tracking regulator in a PG-TO263-5 package. It is designed to supply off-board systems, e.g. sensors in engine management systems under the severe conditions of automotive applications. Therefore, the device is equipped with additional protection functions against reverse polarity and short circuit to GND and battery. With supply voltages up to 40 V, the output voltage follows a reference voltage with high accuracy. The reference voltage can be applied directly to the adjust input or by an external resistor divider. The minimum reference voltage at the components pin is 1.5 V. The output is able to drive loads up to 250 mA following e.g. the 5 V output of a main voltage regulator as reference. The TLE 4252 tracking regulator can be switched into stand-by mode to reduce the current consumption to less than 2A. This feature makes the IC suitable for low power battery applications. This product is also available in a PG-TO252-5 package. See datasheet TLE 4252 D.
