The TLE4275-Q1 is a low-dropout linear regulator designed to connect to the battery in automotive applications. For the new chip, the device has an input voltage range extending to 40V that drives loads up to 500mA. This range allows the device to withstand transients (such as load dumps) that are anticipated in automotive systems. With only a 28µA quiescent current at IOUT = 1mA (new chip), the device is designed for powering always-on components. Microcontrollers (MCUs) and controller area network (CAN) transceivers in standby systems are examples of such components.

The new chip version of the device has state-of-the-art transient response that allows the output to quickly react to changes in load or line (for example, during cold-crank conditions). Additionally, the new chip version has a novel architecture that minimizes output overshoot when recovering from dropout. During normal operation, the device has a tight DC accuracy of ±2.0% over line, load, and temperature (new chip).

The power-good (reset) delay is adjusted by an external capacitor on the delay pin, allowing the delay time to be configured to fit application-specific systems.

The device also incorporates a number of internal circuits for protection against overload and overtemperature. The legacy chip also provides protection against reverse polarity. The legacy chip requires COUT ≥ 22µF with max supported ESR range of ≤ 5Ω and new chip requires COUT ≥ 2.2µF with max supported ESR range of ≤ 2Ω, within the operating temperature range.
