Infineon TLS805B1LDV50XUMA1: Powering Precision with a 50V Low-Dropout Linear Regulator

In the realm of power management, stability and efficiency are paramount. The Infineon TLS805B1LDV50XUMA1 stands out as a high-performance, low-dropout (LDO) linear voltage regulator engineered to deliver exceptional performance in demanding applications. Designed to handle input voltages up to 50V, this component is a robust solution for industrial, automotive, and communications systems where voltage regulation under high input differentials is critical.

Key Features and Advantages

The TLS805B1LDV50XUMA1 offers a fixed output voltage of 5V with a maximum output current of 150mA. Its low dropout voltage ensures high efficiency even when the input voltage is only marginally higher than the output, making it ideal for scenarios involving fluctuating power sources. The device incorporates advanced protection mechanisms including over-current protection (OCP), thermal shutdown, and reverse polarity protection, enhancing system reliability and longevity.

A standout attribute is its very low quiescent current, which minimizes power loss during light-load or standby operations. This is particularly valuable in battery-powered or energy-sensitive applications. Furthermore, the LDO exhibits excellent line and load regulation, maintaining a stable output despite variations in input voltage or output current.

Target Applications

Thanks to its wide input voltage range and robust design, the TLS805B1LDV50XUMA1 is suited for a variety of harsh environments. It is commonly used in automotive power networks, industrial control systems, and as a post-regulator for switching power supplies. Its ability to operate over a broad temperature range aligns with AEC-Q100 guidelines, underscoring its suitability for automotive electronics.
