Infineon TLS835B2ELVXUMA1: High-Performance LDO Voltage Regulator for Automotive and Industrial Applications

In the demanding worlds of automotive electronics and industrial automation, power management is not just a convenience—it is a critical requirement for reliability, safety, and performance. The Infineon TLS835B2ELVXUMA1 stands out as a premier low-dropout (LDO) voltage regulator engineered specifically to meet these rigorous challenges. This device exemplifies the integration of advanced technology with robust design, providing a stable and clean voltage supply to sensitive components such as microcontrollers, sensors, and communication interfaces.

A key strength of the TLS835B2ELVXUMA1 is its exceptional input voltage range from 3.0 V to 40 V, making it incredibly versatile for a wide array of applications. It can handle transient voltage spikes common in automotive environments, such as load dump conditions, ensuring downstream electronics are protected. With a typical dropout voltage of only 280 mV at 150 mA, this LDO maintains regulation even when the input voltage is very close to the output level, enhancing energy efficiency and operational stability.

The device offers a fixed output voltage of 3.3 V or 5.0 V and can deliver a maximum output current of 150 mA, sufficient for powering numerous critical systems. Its high accuracy of ±2% over the entire temperature range ensures that precision components receive consistent power, which is vital for application integrity. Furthermore, the TLS835B2ELVXUMA1 features ultra-low quiescent current, which minimizes power loss during standby modes—a crucial factor for modern energy-conscious designs.

Built with the highest standards of reliability, this LDO incorporates comprehensive protection features including over-current protection (OCP), thermal shutdown (TSD), and reverse polarity protection. These safeguards not only secure the regulator itself but also protect the entire system from potential damage. Its AEC-Q100 qualification confirms its suitability for automotive applications, enduring extreme temperatures and harsh operating conditions.

Housed in a space-saving TSON-10 package, the TLS835B2ELVXUMA1 is designed for high power density boards, offering excellent thermal performance in a minimal footprint. This makes it an ideal choice for space-constrained applications without compromising on power or reliability.

ICGOOODFIND: The Infineon TLS835B2ELVXUMA1 is a top-tier LDO voltage regulator that delivers high performance, robustness, and efficiency for the most demanding automotive and industrial systems. Its combination of a wide input range, low dropout voltage, and integrated protection circuits makes it an exemplary solution for ensuring stable power in challenging environments.
