**ADP130AUJZ-8-R7: A Compact 300mA, Ultra-Low Quiescent Current Linear Regulator**

In the world of portable and battery-powered electronics, power management is paramount. Designers are constantly challenged to extend battery life while maintaining high performance in an increasingly compact form factor. The **ADP130AUJZ-8-R7** from Analog Devices stands out as a critical solution, expertly balancing efficiency, size, and performance.

This linear regulator is engineered to deliver a stable, fixed 1.8V output from an input voltage range of 2.2V to 5.5V, supporting a maximum load current of **300mA**. Its most defining characteristic is its **ultra-low quiescent current (IQ) of just 800 nA** at no load. This remarkably low self-consumption is a game-changer for applications that spend significant time in standby or sleep modes, as it minimizes the constant power drain on the battery, thereby dramatically extending its operational life.

Despite its minimal power draw, the ADP130 does not compromise on performance. It offers excellent line and load regulation, ensuring a stable output voltage even as the input voltage or the current demand from the load fluctuates. Furthermore, key protection features such as **current limiting and thermal shutdown** are integrated, safeguarding both the regulator and the downstream circuitry from potential damage under fault conditions.

Housed in a tiny **5-lead TSOT package**, the ADP130AUJZ-8-R7 is designed for space-constrained applications. Its minimal external component requirement—only input and output capacitors are needed—further reduces the total solution size, making it an ideal choice for compact designs like wearables, medical sensors, and IoT modules.

**ICGOODFIND**: The ADP130AUJZ-8-R7 is a superior choice for designers prioritizing longevity and miniaturization. Its unparalleled combination of ultra-low quiescent current, robust 300mA output capability, and an extremely small footprint makes it an indispensable component for the next generation of power-sensitive portable devices.
