Low quiescent current

Why does quiescent current matter?

In battery-operated systems, the need to achieve high efficiency at no- or light-load conditions requires power solutions to tightly regulate the output while maintaining ultra-low supply current. With TI’s portfolio of ultra-low Iq technologies and products, you can maximize your battery run time and enable low power consumption in your next design.
