Infineon TLS710B0EJV50: 50V Low-Dropout Voltage Regulator for Automotive Applications

In the demanding world of automotive electronics, stability and reliability are paramount. The Infineon TLS710B0EJV50 stands out as a critical component engineered to meet these rigorous requirements. As a 50V low-dropout (LDO) linear voltage regulator, it is specifically designed to provide a stable, clean, and precisely regulated voltage supply to sensitive circuits in the harsh electrical environments found in vehicles.

Automotive systems are subjected to extreme voltage fluctuations, including load dump transients that can push input voltages to dangerously high levels. The TLS710B0EJV50 is built to handle this, featuring a remarkably high maximum input voltage of 50V. This robust capability ensures continuous operation and protection for downstream components, making it an ideal choice for powering microcontrollers, sensors, and infotainment systems directly from the automotive battery line.

A key advantage of this LDO is its low dropout voltage, which allows it to maintain regulation even when the input voltage is only slightly higher than the desired output voltage. This efficiency minimizes power loss and heat generation, a crucial factor for space-constrained and thermally sensitive electronic control units (ECUs). With a fixed output voltage of 5.0V and an output current capability of up to 150 mA, it delivers sufficient power for a wide range of auxiliary functions.

Furthermore, the TLS710B0EJV50 integrates essential protection features that are non-negotiable in automotive design. These include overtemperature shutdown, which prevents thermal runaway, and current limitation, which safeguards the device and the load from short-circuit conditions. Its high immunity to electrical transients and reverse polarity aligns perfectly with automotive standards like AEC-Q100, guaranteeing performance and longevity.

ICGOOODFIND: The Infineon TLS710B0EJV50 is a robust and highly reliable LDO voltage regulator, offering superior performance for 12V and 24V automotive power networks. Its high input voltage tolerance, integrated protections, and stable 5V output make it a cornerstone component for ensuring electronic stability in modern vehicles.
