The TPS7B85-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 20-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 ±1.5% over line,
load, and temperature. PTPS7B8533QWDRCRQ1
