Infineon TLS850B0TBV33: A High-Performance LDO Voltage Regulator for Automotive and Industrial Applications

In the demanding worlds of automotive electronics and industrial control systems, power integrity is non-negotiable. Voltage regulators must deliver unwavering performance under the most challenging conditions, including extreme temperatures, voltage fluctuations, and significant electromagnetic interference. Addressing these critical needs, the Infineon TLS850B0TBV33 stands out as a high-performance, low-dropout (LDO) voltage regulator engineered specifically for robustness and reliability.

This LDO is designed to provide a fixed 3.3V output from an input voltage range of up to 40V, making it exceptionally versatile. Its very low dropout voltage is a key feature, ensuring stable operation even when the input voltage dips very close to the output level, which is crucial for cold-crank and start-stop scenarios in vehicles. Furthermore, the device boasts an impressively low quiescent current in both active and standby modes, significantly reducing the overall power consumption of the system—a vital factor for always-on applications.

Beyond its core regulation function, the TLS850B0TBV33 is packed with advanced protection and diagnostic features that are mandatory in safety-critical applications. These include over-current protection (OCP), over-temperature shutdown (OTSD), and reverse polarity protection. Its high immunity to transients and its wide operating temperature range (-40°C to 150°C junction temperature) ensure reliable performance in harsh under-the-hood automotive environments or on noisy factory floors.

Compliance with stringent automotive standards is a hallmark of this component. It is AEC-Q100 qualified, guaranteeing its reliability for automotive use cases. The device also offers excellent electromagnetic compatibility (EMC), minimizing both its susceptibility to and emission of noise, which simplifies overall system design.

In summary, the Infineon TLS850B0TBV33 is more than just a voltage regulator; it is a comprehensive power management solution. Its combination of a wide input range, low dropout, ultra-low quiescent current, and robust integrated protection makes it an ideal choice for powering microcontrollers, sensors, and CAN transceivers in applications where failure is not an option.

ICGOOFind: The Infineon TLS850B0TBV33 is a premier choice for designers seeking a robust, efficient, and feature-rich LDO regulator. Its automotive-grade qualification and exceptional performance characteristics make it perfectly suited for ensuring stable power in the most demanding automotive and industrial systems.
