TLE4254GSXUMA1

The TLE4254GS is a monolithic integrated low dropout Voltage Tracking Regulator with high accuracy. The IC is designed to supply OFF-board systems, sensors in power-train 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 very 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 70mA while the device follows with high accuracy the 5V output of a main voltage regulator acting as reference.

• Very tight output tracking tolerance to reference
• Flexibility of output voltage adjust higher/lower than reference, proportional to reference voltage
• Status output to indicate short circuits at the output
• Combined reference/enable input
• Very low current consumption in OFF mode
• Input protected against reverse polarity
• Overtemperature protection
• Stable with 1µF ceramic output capacitor
• Output voltage adjust down to 2V
