Description

General part information

TPS7B88-Q1 Series

The TPS7B88-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 40 V, which allows the device to withstand transients (such as load dump) that are anticipated in automotive systems. With only a 17-µA quiescent current at light loads, the device is an optimal solution for powering always-on components such as microcontrollers (MCUs) and controller area network (CAN) transceivers in standby systems.

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 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.

The device is available in thermally conductive packaging to allow the parts to efficiently transfer heat to the circuit board.
