Description

The TL720M05-Q1 is a low-dropout linear regulator designed to connect to the battery in automotive applications. The device has an input voltage range extending to 40V (new chip). This range allows the device to withstand transients (such as load dumps) that are anticipated in automotive systems. With only a 17µA quiescent current at light loads, the device is designed for powering always-on components. Examples of such components are microcontrollers (MCUs) and controller area network (CAN) transceivers in standby systems. The device (new chip) has a 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 device has a novel architecture that minimizes output overshoot when recovering from dropout. During normal operation, the device has a tight DC accuracy of ±1.15% over line, load, and temperature (new chip). 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 TL720M05-Q1 is available in thermally conductive packaging to allow the device to efficiently transfer heat to the circuit board.
