概述
Description
TPS76918QDBVRQ1 is TI’s fixed 1.8-V low-dropout regulator (LDO) in the TPS769 family. It sources a stable 1.8 V rail from a typical 2.7–6.5 V supply (suitable for automotive/industrial use) and can deliver up to about 150 mA. The device is designed for low quiescent current, good line/load regulation, and quiet operation. It includes protection features such as enable control, thermal shutdown, and current-limit protection. The suffix QDBVRQ1 indicates automotive-grade (AEC-Q100 qualified, Q1) in a DBV package (SON-8) with reel packaging. This part is commonly used for automotive electronics and other applications needing a compact, efficient 1.8 V supply. For exact electrical specs, pinout, and packaging, consult the TPS76918QDBVRQ1 datasheet and TI product page.
