**ADP130AUJZ-2-R7: A 300mA, Ultra-Low Quiescent Current CMOS Linear Regulator**

In the realm of power management for portable and battery-powered devices, efficiency is paramount. The **ADP130AUJZ-2-R7** from Analog Devices stands out as a critical component engineered to extend battery life and enhance performance in space-constrained applications. This CMOS linear regulator delivers a robust **300mA output current** while maintaining an exceptionally **ultra-low quiescent current of just 30 µA**. This combination makes it an ideal solution for applications where every microwatt of power counts.

The core strength of the ADP130 lies in its ultra-low ground current, which remains stable across variations in load current and input voltage. This characteristic is vital for applications that spend a significant amount of time in standby or sleep modes, such as wireless sensors, medical wearables, and always-on consumer electronics. By minimizing the current drawn when regulating light loads, the ADP130 ensures that **battery life is significantly extended**, a non-negotiable requirement for modern portable designs.

Beyond its impressive quiescent current, the ADP130AUJZ-2-R7 offers a high power supply rejection ratio (PSRR), which is crucial for powering noise-sensitive components like RF transceivers and precision analog sensors. Its low dropout voltage ensures stable operation even as the battery voltage decays, maximizing the usable energy from the power source. Housed in a compact **5-lead TSOT package**, it provides an excellent power-density solution for PCB layouts where real estate is severely limited.

Designers will also appreciate the regulator's fixed-output voltage version, which simplifies the design process by reducing external component count. Built-in protection features, including current limit and thermal shutdown, ensure safe and reliable operation under fault conditions.

**ICGOODFIND**: The ADP130AUJZ-2-R7 is a superior choice for designers prioritizing ultra-low power consumption, high efficiency, and a small solution size. Its exceptional performance in extending battery runtime makes it a cornerstone component for the next generation of power-sensitive portable devices.
