Product Summary

The TLE4251G is a monolithic integrated low-drop voltage tracker in the very small SMD package P-TO252-5-1. It is designed to supply e.g. sensors under the severe conditions of automotive applications. Therefore the TLE4251G is equipped with additional protection functions against over load, 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.

Parametrics

TLE4251G absolute maximum ratings: (1)Input Voltage: – 42 to 45 V; (2)Output Voltage: –2 to 45 V; (3)Junction temperature: – 40 to 150 ℃; (4)Storage temperature: – 50 to 150 ℃.

Features

TLE4251G features: (1)Output tracking tolerance ≤ ± 0.2%; (2)400 mA output current capability; (3)Enable Function; (4)Very low current consumption in OFF mode; (5)Wide operation range: up to 40 V; (6)Wide temperature range: -40 ℃ ≤ Tj ≤ 150 ℃; (7)Output protected against short circuit; (8)Overtemperature protection; (9)Reverse polarity proof.
