TLE4250G

Low-Drop Voltage Tracker TLE 4250 G Features Output tracking tolerance ≤ ± 0.5% 50 mA output current Combined Tracking/Enable input Very low current consumption in off mode Low drop voltage Suitable for use in automotive electronics Wide operation range: up to 40 V Wide temperature range: – 40 °C ≤ Tj ≤ 150 °C Output protected against short circuit Overtemperature protection Reverse polarity proof Very small SMD-Package SCT 595 Ordering Code Q67006-A9351 SCT 595 Type TLE 4250 G Package SCT-595 (SMD) Functional Description The TLE 4250 G is a monolithic integrated low-drop voltage tracker in the very small SMD package SCT 595. It is designed to supply e.g. sensors under the severe conditions of automotive applications. 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 at the adjust input. Therefore the Adjust pin has to be connected to a reference voltage, e.g. to a 5 V supply on a micro-controller port. The output is able to drive a load up to 50 mA while it follows the output of a main voltage regulator within an accuracy of 0.5%. The TLE 4250 G can be switched in stand-by mode via the adjust input which causes the current consumption to drop to very low values. This feature makes the IC suitable for low power battery applications. Data Sheet Rev. 2.2 1 2000-10-04 TLE 4250 G ADJ 1 5 GND GND 2 Ι 3 4 Q...
