Automotive 150-mA, 40-V, low-dropout (LDO) linear regulator with fast transient response | DCY | 4 | -40 to 125

The TPS7B83-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 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% over line, load,

and temperature.
