PMIC (Power Management ICs) are integrated circuits that are used to efficiently manage, as well as distribute and regulate power in a system. Voltage references (VRs) are among the most important type of PMICs, which are used to regulate and provide a precise voltage output from the input voltage of a system. Such voltage references are important to ensure reliable and accurate voltage level for a wide range of applications. One such PMIC, called the ADR392AUJZ-R2, is a precision voltage reference with a very low dropout voltage.

Applications

The ADR392AUJZ-R2 PMIC can be used in a wide range of applications and systems that require precise voltage levels to function properly. It is ideal for applications like audio amplifiers, home theater systems, and medical equipment, where stable and precise reference voltages are a must. Moreover, since the device has a very low dropout voltage of 0.3V, it is also suitable for low voltage applications such as battery-operated systems and portable electronics.

Working Principle

The ADR392AUJZ-R2 device is a precision voltage reference, which means that it is able to output a very precise, stable voltage regardless of the input voltage. It achieves this by using an internal reference voltage, which is regulated by different control methods. Basically, it is able to control its output voltage by monitoring the voltage on its output pin, and adjusting its internal reference voltage accordingly. This ensures that the voltage output remains stable and within a certain tolerance.

Furthermore, the PMIC has a very low dropout voltage, which helps it to regulate the output voltage even if there is a significant difference between the input and output voltages. This feature is especially helpful in battery-powered applications, where input voltages can sometimes drop significantly due to battery discharge. In such cases, the PMIC helps to ensure that the output voltage remains as accurate as possible.

Conclusion

The ADR392AUJZ-R2 is a precision voltage reference PMIC designed for a wide range of systems and applications that require stable and precise reference voltages. Its very low dropout voltage also makes it suitable for battery-operated applications. It works by monitoring the voltage at its output and adjusting its internal reference voltage accordingly, thus allowing it to provide highly accurate and stable output voltages.
