Quality Control: Learn More
The Rohm Semiconductor BU19UA3WNVX-TL is a positive fixed output linear voltage regulator IC designed for demanding applications. This component delivers a stable 1.9V output with a maximum current capability of 300mA. It features an enable pin for flexible control and offers excellent power supply rejection ratio (PSRR) of 70dB at 1kHz, minimizing noise in sensitive circuits. Protection features include over-current and over-temperature shutdown, enhancing system reliability. With a low quiescent current of 90 µA and a dropout voltage of 0.32V at 300mA, it is suitable for power-sensitive designs. The BU19UA3WNVX-TL is supplied in a compact SSON004X1010 package, ideal for surface mount assembly, and is available on tape and reel. This device finds utility in various industrial and consumer electronics sectors requiring efficient voltage regulation.
