TPS7B8401QWDRBRQ1 General Description

The TPS7B84-Q1 linear regulator is a game-changer for automotive applications, with its impressive 40V input voltage range and ability to withstand transients like load dump. Its low quiescent current of 18µA makes it perfect for always-on components such as MCUs and CAN transceivers in standby systems. With fixed and adjustable output options, it can power a wide range of devices, from SiC gate drivers to microphones and processors. Its state-of-the-art transient response ensures quick reactions to load or line changes, while its novel architecture minimizes output overshoot during recovery. The device maintains a tight DC accuracy of ±0.75% over line, load, and temperature, delivering consistent performance across various conditions. Available in SOT223 and VSON packages, it boasts a compact PCB design and low thermal resistance for sustained operation under high dissipation
