Infineon TLS715B0EJV50: Low-Dropout Linear Voltage Regulator for Automotive and Industrial Applications

In the demanding worlds of automotive electronics and industrial control systems, power management is paramount. Components must deliver unwavering reliability under harsh conditions, including extreme temperatures, voltage fluctuations, and significant electromagnetic interference. Addressing these critical needs, the Infineon TLS715B0EJV50 stands out as a robust and highly integrated low-dropout (LDO) linear voltage regulator.

This LDO regulator is engineered to provide a precise, stable, and clean 5V output voltage from an input voltage range of up to 45V. Its very low dropout voltage is a key feature, ensuring efficient regulation even when the input voltage is only marginally higher than the output level. This capability is crucial in automotive applications, such as during cold-crank scenarios where the battery voltage can momentarily dip to very low levels, yet the connected systems must continue to operate without interruption.

Beyond its voltage regulation prowess, the TLS715B0EJV50 is packed with integrated protection features that make it exceptionally durable. It boasts built-in over-current protection (OCL), over-temperature protection (OTP), and reverse polarity protection. This comprehensive suite safeguards both the regulator itself and the downstream circuitry from potential damage caused by fault conditions, a non-negotiable requirement in safety-critical automotive and industrial environments.

Furthermore, the device includes an enable pin for remote on/off control, allowing for power sequencing and energy-saving shutdown modes in modern electronic architectures. Its low quiescent current makes it suitable for applications that are sensitive to power consumption. Housed in a space-saving PG-TO252-3-11 package, it offers an excellent thermal performance, efficiently dissipating heat to maintain operational stability.

ICGOOODFIND: The Infineon TLS715B0EJV50 is a superior LDO voltage regulator that combines high input voltage tolerance, ultra-low dropout, and a robust set of protective features. It is an ideal, reliable power management solution designed to meet the stringent quality and durability standards of the automotive and industrial sectors.
