The TLE4253GS is a monolithic integrated low dropout Voltage Tracking Regulator with exposed pad offers extremely low thermal resistance. The IC is designed to supply OFF-board systems, sensors in engine management systems under the severe conditions of automotive applications. Therefore, the IC is equipped with additional protection functions against reverse polarity and short circuit to GND and battery. With supply voltages up to 40V, the output voltage follows a reference voltage applied at the adjust input with high accuracy. The reference voltage applied directly to the adjust input or by an external resistor divider can be 2V at minimum. The output is able to drive loads up to 250mA at minimum while the device follows the 5V output of a main voltage regulator acting as reference with high accuracy. The TLE4253 tracker can be set into shutdown mode in order to reduce the quiescent current to an extremely low value. This makes the IC suitable to low power battery applications.
