Infineon TLS810B1LDV50XUMA1: A 50V Low-Dropout Linear Voltage Regulator for Demanding Applications

In the realm of power management, ensuring stable and clean voltage supply is paramount, especially in automotive, industrial, and communications systems where electrical noise and wide input voltage ranges are common challenges. The Infineon TLS810B1LDV50XUMA1 stands out as a robust solution, a 50V Low-Dropout (LDO) linear voltage regulator engineered for high-reliability performance in harsh environments.

This regulator is designed to deliver a fixed 5.0V output with a remarkable maximum input voltage capability of 50V. Its key advantage lies in the very low dropout voltage, typically 200 mV at a 150 mA load. This means it can continue to regulate the output voltage effectively even when the input voltage dips very close to the output level, preserving system functionality and enhancing energy efficiency. Furthermore, the device incorporates advanced protection features, including overcurrent protection (OCP), overtemperature shutdown (TSD), and reverse polarity protection, safeguarding both the regulator itself and the sensitive load it powers.

The TLS810B1LDV50XUMA1 excels in providing an exceptionally clean and low-noise output, critical for powering noise-sensitive components like sensors, microcontrollers, and RF circuits. Its high power supply rejection ratio (PSRR) at lower frequencies effectively attenuates ripple and noise from the input source. Housed in a space-efficient TSOP-6 package, it is an ideal choice for compact PCB designs. Typical applications span from always-on automotive systems (e.g., infotainment, ADAS) to industrial control systems and battery-powered equipment, where stable voltage under fluctuating conditions is non-negotiable.

ICGOOODFIND: The Infineon TLS810B1LDV50XUMA1 is a high-performance LDO regulator that combines a high input voltage rating, low dropout, and excellent noise performance with integrated protection features, making it a superior and reliable choice for demanding power management tasks.
