**ADP160ACBZ-8-R7: An Ultra-Low Quiescent Current 200mA CMOS Linear Regulator**

In the realm of power management for portable and battery-powered devices, efficiency is paramount. The **ADP160ACBZ-8-R7** from Analog Devices stands out as a critical component, engineered to extend battery life by minimizing power loss even when the system is in a standby or active-but-lightly-loaded state. This ultra-low dropout (LDO) linear regulator delivers a stable, fixed 1.8V output with a impressive maximum output current of 200mA, making it an ideal power solution for a wide array of applications.

The defining characteristic of the ADP160ACBZ-8-R7 is its **ultra-low quiescent current (IQ)**. At a mere 800 nA (typical) under no-load conditions, this regulator ensures that a negligible amount of power is drawn from the battery when the system is idle. This is a vital feature for devices that spend a significant portion of their operational life in sleep or standby modes, such as wireless sensors, medical health monitors, and always-on IoT endpoints. By drastically reducing this ground current, the regulator helps achieve **significantly extended battery life**, moving from months to years of operation in many cases.

Built on a CMOS process, this LDO offers a very low dropout voltage of only 200 mV at the full 200 mA load. This high efficiency in voltage conversion allows it to maintain a stable output even when the input voltage dips very close to the output level, preserving functionality as battery voltage decays over time. Furthermore, the device incorporates excellent line and load regulation, ensuring a clean and stable 1.8V supply that is immune to noise and fluctuations on the input bus, which is crucial for powering noise-sensitive components like microcontrollers, sensors, and RF modules.

The ADP160ACBZ-8-R7 comes in a compact, 4-bump WLCSP (Wafer Level Chip Scale Package), making it perfectly suited for space-constrained PCB designs. Its feature set is rounded out with built-in protection mechanisms, including current limiting and thermal shutdown, safeguarding both the regulator and the downstream circuitry from fault conditions.

**ICGOODFIND**: The ADP160ACBZ-8-R7 is a superlative choice for designers prioritizing **extreme power efficiency** and miniaturization. Its unparalleled ultra-low quiescent current makes it a cornerstone technology for the next generation of long-life, battery-connected electronics.
