Infineon TLE42662GSV33HTMA2: A 3V Low-Drop Voltage Regulator for Automotive Applications

In the demanding world of automotive electronics, ensuring a stable and reliable power supply is paramount. The Infineon TLE42662GSV33HTMA2 stands out as a quintessential component designed to meet this critical need. This integrated circuit is a low-dropout (LDO) linear voltage regulator that delivers a fixed, precisely regulated output voltage of 3.3V, making it an ideal power management solution for a vast array of automotive applications, from sensors and control units to infotainment systems.

A key feature of this regulator is its remarkably low dropout voltage. This characteristic allows it to continue providing a stable 3.3V output even when the input voltage dips to a level very close to the output voltage, as low as 3.6V. This capability is crucial in the automotive environment, where voltage swings, such as those during cold-crank conditions, are common. By maintaining regulation with such a small voltage headroom, the TLE42662GSV33 ensures that connected microcontrollers and ICs continue to operate without interruption, enhancing overall system reliability.

Beyond its core regulation function, the TLE42662GSV33HTMA2 is engineered with a comprehensive suite of built-in protection features that are essential for the harsh automotive ecosystem. These include overcurrent protection (OCL) to safeguard the device and the load during fault conditions, overtemperature protection (OTP) to shut down the regulator before thermal damage can occur, and reverse polarity protection, offering resilience against accidental battery misconnection. Furthermore, its very low quiescent current in standby mode makes it suitable for applications requiring always-on functionality without draining the vehicle's battery.

The device is qualified for the rigorous AEC-Q100 standard, confirming its reliability for use in automotive applications across a wide temperature range. Its robust design, housed in a PG-TO263-5-11 (DPAK-5) package, ensures effective heat dissipation and mechanical durability on the PCB.

ICGOOFind: The Infineon TLE42662GSV33HTMA2 is a robust and highly reliable 3.3V LDO voltage regulator specifically designed to withstand the challenges of the automotive environment. Its exceptionally low dropout voltage, comprehensive protection mechanisms, and AEC-Q100 compliance make it a superior choice for powering electronic control units (ECUs), sensors, and other critical systems where stable voltage is non-negotiable.
