As smart terminals such as smartphones, AR glasses, and laptops are accelerating their evolution toward being lighter, thinner, and more highly integrated, the ultimate utilization of millimeter-level space has become a core competitiveness in product design. As an innovation pioneer in the field of power management, Awinic proudly launches ultra-small package LDOs (low-dropout linear regulators), creating precisely adapted power solutions for compact electronic products. While effectively improving space utilization, they also inject new momentum into the lightweight and thin design of devices.

Compared with the mainstream DFN package of 1mm×1mm×0.37mm, Awinic's ultra-small package LDO has its size reduced to 0.645mm×0.645mm with a thickness of only 0.3mm. Its area is sharply reduced by 60% compared with the DFN package, which greatly improves space utilization. This change frees up more layout space for precision components such as camera modules and sensors, perfectly meeting the design requirements for extreme thinness and lightness of smart terminals.
While achieving an extremely small size, the chip still maintains the characteristics of low dropout voltage, low noise, high power supply rejection ratio and excellent transient response. It can provide stable power output and a pure power supply environment for smart terminals such as smartphones, AR glasses and laptops, laying a solid foundation for the stable operation of the devices.
