Overview

The TLS115D0EJXUMA1 is a high-precision automotive linear voltage tracker designed to provide a stable supply for off-board sensors. This AEC-Q100 qualified regulator can deliver up to 150mA with a high tracking accuracy of +/-5 mV, ensuring that remote sensors operate at the same reference level as the local microcontroller.

Why Choose This Part

This regulator offers robust protection features including reverse polarity, short circuit, and over-temperature protection. It is optimized for stability with low-ESR ceramic output capacitors and features a very high PSRR of 85dB at 100Hz to filter out supply noise.

Applications

Off-board Sensor Supply
Provides a precise voltage reference to remote sensors, maintaining signal integrity over long cable runs in automotive environments.
Automotive ECU Power
Used within Electronic Control Units to provide auxiliary regulated power with low quiescent current of 55uA.
Powertrain Control Systems
Reliable operation in harsh under-the-hood conditions with a junction temperature rating up to 150 degrees Celsius.
