Infineon TLE4296GV50HTSA1 5V Low-Dropout Voltage Regulator: Features and Applications

The Infineon TLE4296GV50HTSA1 is a robust low-dropout (LDO) voltage regulator designed to deliver a precise, stable 5V output from a higher input voltage. As a critical component in power management systems, it is engineered for applications where reliability, efficiency, and compactness are paramount. This LDO is particularly well-suited for automotive electronics, industrial control systems, and portable devices, where maintaining voltage integrity under varying load conditions is essential.

Key Features

One of the standout attributes of the TLE4296GV50HTSA1 is its very low dropout voltage, typically as low as 200 mV at full load. This allows the device to continue regulating the output voltage effectively even when the input voltage is only slightly above the 5V threshold, enhancing energy efficiency and extending battery life in portable applications. The regulator can supply a maximum output current of 150 mA, making it ideal for powering microcontrollers, sensors, and other low-power ICs.

The device incorporates multiple protection mechanisms, including overtemperature shutdown, short-circuit protection, and reverse polarity protection. These features ensure operational safety and longevity, even in harsh environments. Additionally, it offers low quiescent current consumption, which minimizes power loss when the load is light or in standby mode. The TLE4296GV50HTSA1 is housed in a small PG-TO252-3 (DPAK) package, providing excellent thermal performance while saving board space.

Typical Applications

Thanks to its robust design and protective features, this LDO is extensively used in automotive electronic systems, such as infotainment units, dashboard instrument clusters, and body control modules. Its ability to operate reliably over a wide temperature range (-40°C to 150°C) makes it perfect for under-the-hood applications and other demanding automotive scenarios.

In industrial automation, the regulator powers control logic, PLCs, and sensor interfaces, where voltage stability is critical to system accuracy. Furthermore, its low dropout and efficiency characteristics suit battery-powered devices like handheld meters, IoT nodes, and consumer electronics, helping to maximize runtime.
