The TLE4269GLXUMA1 IC from Infineon Technologies is a linear voltage regulator that is part of its PMIC portfolio, specifically within its range of voltage regulators. A voltage regulator’s main purpose is to keep power output at a constant voltage even with fluctuations in the input voltage. This is useful in automotive applications in which voltage surges can occur. The TLE4269GLXUMA1 is specifically tailored towards modern automotive as well as industrial applications, that require highly efficient and accurate voltage regulation.

The TLE4269GLXUMA1 is designed to integrate with larger systems and requires minimal external components to achieve effective voltage regulation. The package is a small, low-profile WLG-12 package with a low thermal resistance output transistor. This ensures that the device can be properly placed in automotive applications to fit in limited spaces, as well as that it does not generate a lot of excess heat which can cause it to overheat or malfunction, ensuring a high degree of reliability.

In terms of its actual performance, the TLE4269GLXUMA1 is an excellent choice for applications that need a wide voltage input range, with the device handling between 7V to 40V (50V for short durations). This input range is much wider than for other linear regulators, which makes it suitable for wide operation conditions in harsher environments. The regulator also features a good efficiency, as well as accurate output voltage, which can be adjustable through external resistors. Moreover, considering that the device is also equipped with overvoltage, continuous current limitation, and overtemperature protection, it can handle tough and challenging scenarios while keeping the system safe.

On the feature side, the TLE4269GLXUMA1 comes equipped with two enable pins, a fault pin and an overvoltage protection (OVP) pin. The two enable pins offer either a shutdown operation or a standby mode. When the enable pins are off, no current is drawn from the regulator and it enters the shutdown mode. The fault pin informs the user of a fault in the system, and it is active-low so that when it is low, a fault has occurred. The OVP pin is activated when the output voltage exceeds the OVP threshold. This prevents situations in which the device could be damaged by an overvoltage.

The TLE4269GLXUMA1 is an excellent linear voltage regulator for automotive and industrial applications. Its wide voltage input range and power protection features make it suitable for conditions in which reliable and accurate voltage regulation is required. Moreover, its low package, 1x4 WLG-12, makes it easy and efficient to integrate with larger systems. In short, the TLE4269GLXUMA1 from Infineon Technologies is a great choice for automotive and industrial applications that require high reliability, low thermal resistance and efficient voltage regulation.
