Infineon TLS710B0EJV50XUMA1 50V Low-Dropout Voltage Regulator: Key Features and Applications

The Infineon TLS710B0EJV50XUMA1 is a high-performance, low-dropout (LDO) voltage regulator designed to deliver a stable and precise 5.0V output from input voltages as high as 50V. This device is engineered to meet the demanding requirements of modern automotive and industrial applications, where robust performance and reliability are paramount. Its ability to operate with a very low dropout voltage—even at high input voltages—makes it an exceptional choice for power conditioning in harsh electrical environments.

Key Features

A standout feature of this LDO is its exceptionally wide input voltage range of up to 50V. This allows it to handle significant voltage transients and surges commonly found in automotive systems, such as load-dump events, without being damaged. Furthermore, it boasts a very low dropout voltage, ensuring regulation is maintained even when the input voltage is only slightly above the output level, which maximizes efficiency and extends operational range.

The device incorporates comprehensive protection mechanisms to safeguard both itself and the downstream circuitry. These include current limiting, overtemperature shutdown, and reverse polarity protection. The inclusion of an enable pin allows for external control of the regulator's operation, facilitating power management and sleep modes to reduce overall system quiescent current.

Designed for reliability, the TLS710B0EJV50XUMA1 is AEC-Q100 qualified, making it a trusted component for automotive applications. It is offered in a space-saving, surface-mount PG-SOT223-4 package, which provides good thermal performance for its size.

Primary Applications

The combination of high input voltage tolerance and automotive-grade qualification makes this LDO ideal for a wide array of uses:

Automotive Electronics: It is perfectly suited for powering sensors, control units (ECUs), infotainment systems, and clusters directly from the vehicle's battery line, ensuring stable operation despite voltage fluctuations.

Industrial Automation: In factory settings with 24V systems, this regulator can provide a clean 5V rail for microcontrollers, sensors, and communication modules, protecting them from noise and voltage spikes.

Telecommunications: Used to regulate power for interface circuits and monitoring equipment that must operate reliably from unstable power sources.

Consumer Electronics: Applicable in products requiring robust power management for peripherals or specific sub-circuits.
