Description

General part information

TPS7B84-Q1 Series

The TPS7B84-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 an 18-µA quiescent current, 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 TPS7B84-Q1 has both fixed and adjustable output types. The wide output voltage range allows the device to generate the bias voltage for silicon carbide (SiC) gate drivers and microphones as well as power MCUs and processors.

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 ±0.75% over line, load, and temperature.
