Infineon IFX91041EJV50: High-Performance 5V Voltage Regulator for Automotive and Industrial Applications

In the demanding worlds of automotive electronics and industrial control systems, power integrity is non-negotiable. The Infineon IFX91041EJV50 stands out as a high-performance 5V linear voltage regulator engineered specifically to meet the rigorous requirements of these applications. This device delivers a stable, clean, and precisely regulated 5V supply from a higher input voltage, serving as a reliable power source for sensitive microcontrollers, sensors, and ASICs.

A key strength of the IFX91041EJV50 is its exceptional robustness and wide operating temperature range, making it perfectly suited for the harsh environments found under the hood of a vehicle or on a factory floor. It features a very low dropout voltage, ensuring stable operation even when the input voltage dips close to the output level, which is critical for cold-crank and start-stop scenarios in automobiles. Furthermore, the regulator incorporates comprehensive protection features, including over-current protection (OCP), thermal shutdown (TSD), and reverse polarity protection, safeguarding both itself and the downstream circuitry from potential damage.

The component's very low quiescent current enhances energy efficiency, a vital parameter for always-on systems. Its design prioritizes low electromagnetic emissions (EMI), helping systems comply with strict automotive EMC standards without the need for additional filtering components. Packaged in a space-saving, surface-mount PG-TO263-5-11 package, it also offers excellent thermal performance for effective heat dissipation.

ICGOOODFIND: The Infineon IFX91041EJV50 is a premier choice for designers seeking a robust, feature-rich, and reliable 5V power solution. Its combination of automotive-grade durability, integrated protection mechanisms, and high-performance characteristics makes it an indispensable component for creating resilient electronic systems in automotive and industrial markets.
