ADP122AUJZ-2.9-R7 - Low Dropout Linear Regulator by Analog Devices Inc.

The ADP122AUJZ-2.9-R7 is a high-performance, low dropout linear regulator (LDO) designed and manufactured by Analog Devices Inc., a leading company in the field of high-performance analog, mixed-signal, and digital signal processing integrated circuits. This LDO is engineered to deliver a fixed output voltage of 2.9V with an output current of up to 300 mA, making it an ideal choice for a wide range of applications where power efficiency and voltage regulation are critical.

With its low quiescent current of just 180 µA (typical), the ADP122AUJZ-2.9-R7 is optimized for battery-powered devices, helping to extend the operational lifespan by minimizing power drain when in standby mode. The device operates over a wide input voltage range from 2.3V to 5.5V, providing flexibility in various power supply scenarios and ensuring consistent performance even with input voltage fluctuations.

The ADP122AUJZ-2.9-R7 comes in a compact, 5-lead TSOT package, which is highly suitable for space-constrained applications. It features a low dropout voltage of only 110 mV at 300 mA load, which allows for efficient operation close to the input voltage and reduces power loss, thus improving overall system efficiency.

This LDO also includes several safety and performance-enhancing features such as over-current protection and thermal overload protection, ensuring reliable operation under a variety of conditions. The presence of a no-load stability feature allows the regulator to remain stable and operational even when the output load is disconnected, preventing any potential issues in dynamic load conditions.

With its excellent load and line regulation characteristics, the ADP122AUJZ-2.9-R7 maintains a stable output voltage despite changes in load current or variations in the input voltage. This level of performance, combined with its low noise operation, makes it an excellent choice for sensitive RF and analog circuitry, portable and handheld devices, and any application where a stable and efficient power supply is necessary.

To facilitate easy integration into various designs, the ADP122AUJZ-2.9-R7 is fully specified over the −40°C to +125°C temperature range, providing reliable operation across a broad spectrum of environmental conditions. Whether you are designing for consumer electronics, medical devices, or industrial applications, this LDO from Analog Devices Inc. offers a robust and efficient power management solution.
