**ADP162AUJZ-3-R7: A 3V, 500mA Ultra-Low Quiescent Current LDO Regulator**

In the realm of power management, efficiency is paramount, especially for battery-powered and always-on applications. The **ADP162AUJZ-3-R7** from Analog Devices stands out as a high-performance, fixed 3V output **low-dropout (LDO) linear regulator** engineered to meet the stringent demands of modern electronic systems. This device delivers a robust **500mA output current** while maintaining exceptional power efficiency, a combination that makes it an ideal choice for a wide array of portable and industrial devices.

A defining characteristic of this LDO is its **ultra-low quiescent current (IQ)**, typically a mere 3.5 µA. This feature is critically important for applications that spend a significant amount of time in standby or sleep modes, as it **minimizes the drain on the battery**, thereby extending its operational life. Whether it's a wireless sensor node, a medical health monitor, or a handheld meter, the ADP162 ensures that power is conserved without compromising performance when the system is active.

Beyond its low IQ, the regulator boasts an impressively **low dropout voltage** of only 145 mV at a 500 mA load. This allows the device to continue regulating its 3V output even when the input voltage dips very close to that level, maximizing the usable energy from a discharging battery or an unregulated power supply. Furthermore, the ADP162 is designed for stability and requires only a small, space-saving 1 µF ceramic output capacitor, simplifying board design and reducing the overall bill of materials.

The device incorporates key protection features such as **current limit and thermal shutdown**, safeguarding both the regulator and the downstream circuitry under fault conditions. Housed in a compact 5-lead TSOT package, the ADP162AUJZ-3-R7 offers a powerful and reliable power management solution in a minimal footprint.

**ICGOODFIND:** The ADP162AUJZ-3-R7 is a superior LDO regulator that excels in providing high current, stable voltage, and outstanding power efficiency. Its ultra-low quiescent current and low dropout voltage make it an exceptional component for enhancing battery life and reliability in power-sensitive applications.
