Low Quiescent Current Solutions

ROHM Low Quiescent Current Solutions increase the demand for smaller components that provide greater design flexibility and the necessary space for integrating features. These regulators achieve lower power consumption to prolong battery life. The low-quiescent-current regulators offer a maximum rated voltage of 50V, an output current ranging from 200mA to 500mA, and a Quiescent current as low as 6μA. These low-current-consuming products are ideal for compact battery-driven devices in applications like smartphones, IoT, wearables, and portable equipment.
