LQ05021RCS4

LQ05021RCS4 is an ultimate efficient, 2A rated integrated load switch with slew rate control. Its outstanding performance in efficiency makes this an ideal solution for applications like IoT, mobile and wearable. This remarkable device incorporates cutting-edge technology that achieves industry-leading performance in terms of the lowest quiescent current (IQ), and shutdown current (ISD). The low IQ and ISD solutions empower designers to curtail parasitic leakage current, enhance system efficiency, and extend battery lifespan. The integration of slew rate control within the LQ05021QCS4 serves as a critical enhancement to system reliability, effectively mitigating voltage swings on the bus during switching events. It is used in applications such as mobile devices, data storage, SSD, IoT devices, wearables, low power subsystems.
