Infineon TLS850D0TAV50: A High-Performance 5V Low-Dropout Voltage Regulator for Automotive and Industrial Applications

In the demanding environments of modern automotive and industrial systems, stable and reliable power supply is non-negotiable. The Infineon TLS850D0TAV50 addresses this critical need as a high-performance 5V low-dropout (LDO) voltage regulator designed to deliver exceptional efficiency, accuracy, and robustness. This device ensures that sensitive microcontrollers, sensors, and other critical components receive clean and stable power, even under the most challenging conditions.

A key strength of the TLS850D0TAV50 is its extremely low dropout voltage, which enables it to continue regulating the output voltage even when the input voltage is very close to the 5V output level. This characteristic is vital for automotive start-stop scenarios, where the battery voltage can dip significantly during engine cranking. The LDO ensures uninterrupted operation of electronic control units (ECUs), preventing system resets or malfunctions.

The regulator boasts outstanding accuracy with a tight output voltage tolerance of ±2% over the entire operating temperature range, load, and input voltage conditions. This precision is crucial for powering analog-to-digital converters and reference circuits where voltage deviations can directly impact measurement accuracy and system performance.

Built with rugged automotive and industrial applications in mind, the TLS850D0TAV50 incorporates a comprehensive suite of protection features. These include overcurrent protection (OCP), overtemperature shutdown (TSD), and reverse polarity protection, safeguarding both the regulator itself and the downstream circuitry from potential damage. Furthermore, its very low quiescent current in standby mode makes it suitable for applications requiring always-on functionality, contributing to overall energy efficiency.

The device operates over a wide input voltage range from 3.0V to 40V, making it exceptionally versatile. It can handle load dump transients typical in automotive electrical systems, ensuring reliable performance against voltage spikes. Its ability to function reliably across a wide temperature range from -40°C to 150°C (junction temperature) qualifies it for use under the hood in automotive environments and in harsh industrial settings.

Packaged in a space-saving, thermally enhanced PG-TO252-5 (DPAK) package, the TLS8500D0TAV50 offers excellent thermal performance, which is essential for dissipating heat under high load conditions.

ICGOODFIND: The Infineon TLS850D0TAV50 stands out as a premier solution for 5V power regulation, masterfully balancing high performance, exceptional robustness, and diagnostic capabilities. Its combination of low dropout voltage, high accuracy, and extensive protection features makes it an ideal and reliable choice for powering the electronic backbone of next-generation vehicles and industrial automation equipment.
