Infineon TLS850B0TEV33: A High-Performance LDO Voltage Regulator for Automotive and Industrial Applications

In the demanding worlds of automotive electronics and industrial automation, power management is not just a requirement—it's a critical factor in system reliability, safety, and performance. The Infineon TLS850B0TEV33 stands out as a robust and highly integrated Low-Dropout (LDO) voltage regulator engineered specifically to meet the stringent challenges of these environments.

This LDO regulator provides a fixed 3.3V output voltage from an input voltage range of up to 40V, making it exceptionally versatile. Its key strength lies in its extremely low quiescent current, which is crucial for modern vehicles and industrial systems that feature "always-on" components, helping to minimize battery drain during standby or key-off phases. Furthermore, the device boasts an impressively low dropout voltage, ensuring stable operation even when the input voltage dips very close to the output level, a common scenario in automotive cold-crank conditions.

Beyond its core regulation function, the TLS850B0TEV33 is packed with advanced protection and diagnostic features. It includes over-current protection (OCP), over-temperature shutdown (OTSD), and a fault signaling output (ERR_N). This makes it an intelligent power solution that not only protects itself but also communicates its status to a host microcontroller, enabling predictive maintenance and enhanced system safety. Its AEC-Q100 qualification underscores its readiness for the toughest automotive applications, from infotainment and ADAS to body control modules.

ICGOOODFIND: The Infineon TLS850B0TEV33 is a premier choice for designers seeking a reliable, feature-rich, and efficient power management solution. Its combination of a wide input range, ultra-low quiescent current, and comprehensive diagnostic capabilities makes it an indispensable component for next-generation automotive and industrial systems where resilience and intelligence are paramount.
