The TLE4252G is a monolithic integrated low-drop voltage tracking regulator in a very small SMD package PG-TO263-5. 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 applied at the adjust input with high accuracy. The reference voltage applied directly to the adjust input or by an e.g. external resistor divider can be 1.5 V minimum. The output is able to drive loads up to 250 mA. The TLE 4252 tracker can be switched into stand-by mode to reduce the current consumption to very low values. This feature makes the IC suitable for low-power battery applications.
