Infineon TLF51801ELV: A High-Performance 150 mA Low-Dropout Voltage Regulator

In the realm of power management for automotive and industrial applications, stability, efficiency, and reliability are paramount. The Infineon TLF51801ELV stands out as a high-performance, low-dropout (LDO) voltage regulator engineered to meet these rigorous demands. Designed to deliver a robust 150 mA output current, this component ensures consistent voltage regulation even when the input voltage is barely above the desired output level, a critical feature for battery-powered and noise-sensitive systems.

A key strength of the TLF51801ELV is its extremely low dropout voltage, which minimizes power loss and maximizes efficiency, thereby extending battery life and reducing heat generation. This is particularly vital in always-on systems found in modern vehicles, such as infotainment and advanced driver-assistance systems (ADAS). Furthermore, the device boasts an impressively low quiescent current in both active and standby modes, enhancing energy efficiency without compromising performance.

The regulator is built for the challenging environments of the automotive sector, featuring a wide input voltage range and operational robustness under harsh conditions. It includes comprehensive protection features such as over-current, over-temperature, and reverse polarity protection, safeguarding both the regulator itself and the downstream components. Its AEC-Q100 qualification guarantees compliance with stringent automotive quality and reliability standards.

With a high power supply rejection ratio (PSRR), the TLF51801ELV effectively filters out noise from the input supply, providing a clean and stable output voltage crucial for powering sensitive analog and digital ICs. Available in a space-saving, thermally enhanced DSO-8 package, it is an ideal solution for compact PCB designs where thermal management is a concern.
