Product Introduction
TPS7B88-Q1 is a low-dropout linear regulator designed for battery-connected automotive applications. With an input voltage range up to 40V, the device can withstand transients that may occur in automotive systems, such as load dump. Its quiescent current of only 17μA at light load makes it an excellent solution for powering always-on devices in standby systems, such as MCUs and CAN transceivers.
The device features advanced transient response, enabling the output to respond quickly to load or line variations (e.g., under cold-crank conditions). In addition, its innovative architecture minimizes output overshoot during recovery from voltage dropout. During normal operation, the device maintains ±1.15% DC accuracy across the full line, load, and temperature range.
The device is housed in a thermally enhanced package that efficiently conducts heat to the PCB.
