TLE4295GV50HTSA1: A 5V Low-Dropout Voltage Regulator for Automotive Applications

In the demanding environment of modern automotive electronics, the stability and reliability of the power supply are paramount. The TLE4295GV50HTSA1 from Infineon Technologies stands out as a quintessential component engineered specifically to meet these rigorous demands. This integrated circuit is a 5V low-dropout (LDO) linear voltage regulator that provides a robust and clean power source for microcontrollers, sensors, and other critical logic circuits within a vehicle.

The core functionality of the TLE4295 is to convert a fluctuating input voltage, typically from the vehicle's battery (ranging from approximately 5.5V to 42V), into a stable, precisely regulated 5V output. Its low-dropout voltage is a critical feature, enabling it to continue regulating the output voltage even when the input voltage dips very close to 5V. This is exceptionally valuable during automotive cold-crank conditions, where the battery voltage can plummet to very low levels, ensuring that connected systems remain operational without a reset.

Beyond basic regulation, the TLE4295GV50HTSA1 is packed with protective features that are indispensable for automotive use. It incorporates overtemperature protection and short-circuit protection, safeguarding both the regulator itself and the downstream components from damage under fault conditions. Furthermore, its very low quiescent current in standby mode makes it suitable for applications requiring always-on functionality, contributing to overall energy efficiency.

Housed in a thermally enhanced PG-TO252-5 (DPAK) package, the regulator is designed to effectively dissipate heat, a necessity given the wide ambient temperature ranges (-40°C to 150°C junction temperature) experienced under the hood. Its AEC-Q100 qualification guarantees that it meets the strict quality and reliability standards required for automotive components, ensuring long-term performance and durability.

ICGOODFIND: The TLE4295GV50HTSA1 is an exemplary automotive-grade LDO regulator, combining precise 5V regulation, a low dropout voltage, and comprehensive protection features in a robust package. It is an ideal, reliable choice for powering electronic control units (ECUs) and other systems in the harsh automotive environment.
