BU19UA3WNVX-TL Description
BU19UA3WNVX-TL Description
The BU19UA3WNVX-TL is a linear regulator IC designed by Rohm Semiconductor, offering a fixed output voltage of 1.9V and a maximum output current of 300mA. This device is housed in a compact SSON004X1010 package, making it suitable for surface-mount applications. The regulator is designed to operate with an input voltage range up to 5.5V, ensuring compatibility with a variety of power sources. With a dropout voltage of only 0.32V at 300mA, the BU19UA3WNVX-TL provides high efficiency even at low input-to-output voltage differentials. This regulator also features low quiescent current (90 µA) and excellent power supply rejection ratio (PSRR) of 70dB at 1kHz, making it ideal for noise-sensitive applications. The device includes enable control and robust protection features such as over-current and over-temperature protection, ensuring reliable operation under various conditions. The BU19UA3WNVX-TL is REACH unaffected and ROHS3 compliant, adhering to stringent environmental and safety standards. It is available in a tape & reel package, facilitating efficient manufacturing processes.
