TPS7B8450QWDRBRQ1 General Description

Unlike traditional regulators, the TPS7B84-Q1 features a novel architecture that prevents output overshoot when recovering from dropout situations. You can rely on tight DC accuracy of ±0.75% across variations in line, load, and temperature. Available in compact SOT223 and VSON packages with wettable flanks, this device simplifies PCB design while offering low thermal resistance for sustained performance under challenging thermal conditions

Key Features

This high-performance regulator is designed for automotive systems that require precision power control
It's ideal for use in applications such as engine management, transmission control, and anti-lock braking systems (ABS)
