Overview

TPS7B84-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 18μA makes it an excellent solution for powering always-on devices in standby systems, such as MCUs and CAN transceivers. The TPS7B84-Q1 is available in fixed and adjustable output versions. The wide input voltage range enables bias voltage generation for SiC gate drivers and microphones, as well as powering MCUs and processors. Advanced transient response allows the output to react quickly to load or line changes, such as during cold-crank conditions. Additionally, the novel device architecture minimizes output overshoot during recovery from voltage dropout. In normal operation, the device maintains ±0.75% DC accuracy across the full line, load, and temperature range. The device is offered in SOT223 and small VSON packages with wettable flanks, enabling compact PCB designs. Low thermal resistance supports sustained operation even under high thermal dissipation across the entire device.
