ADP7102ARDZ-9.0-R7 Application Field and Working Principle

Introduction

The ADP7102ARDZ-9.0-R7 is a voltage regulator manufactured by Analog Devices Inc. It belongs to the PMIC – Voltage Regulators – Linear family. The development of this linear voltage regulator expands its application field, making it suitable for many portable equipments such power tools that require a reliable voltage source.

Features

This device offers several features that makes this regulator very competitive in the market. First of all, the low quiescent current of 150uA per channel makes it an excellent choice for applications in which the voltage supply has to be maintained for extended periods of time with no wasting of energy. Additionally, the ADP7102ARDZ-9.0-R7 is capable of operating with a supply voltage up to 6.5V and delivering up to 1.2A of continuous output current on a dual-channel mode, making it suitable for a wide range of applications. The adjustable output voltage feature also makes this device an attractive option, since it can easily be adjusted according to the specifications of the application.

Functions

The ADP7102ARDZ-9.0-R7 is an excellent choice for portable devices, since the regulator is designed for high input voltage operation with low quiescent current. This allows devices to maintain the voltage supply for an extended period of time, making them ideal for use in applications that require a reliable voltage source. The device also serves as a linear voltage regulator. This means that the output voltage of the regulator can be set to a predetermined level, and the regulator will maintain this output voltage irrespective of the input voltage. This function allows the device to serve as a voltage regulator, ensuring that the input voltage is regulated to the predetermined level regardless of any fluctuations in the input voltage. The device also offers thermal protection and current over-limit protection, which helps to protect the device from any potential damage due to abnormal input or output voltages.

Working Principle

The ADP7102ARDZ-9.0-R7 operates on the principle of linear voltage regulation. This means that it takes the input voltage and converts it into a regulated, fixed output voltage. This is done by comparing the voltage across the regulator to a reference voltage, and adjusting the output voltage accordingly. The device features two channels and each of them can provide an adjustable output between 0.8V and 6.5V and configured in linear mode. When the device is in linear mode, the output voltage is constantly monitored and compared to the reference voltage. If the output voltage differs from the reference, the device will adjust the output voltage accordingly to maintain the predetermined value.

Conclusion

The ADP7102ARDZ-9.0-R7 is a voltage regulator that belongs to the PMIC - Voltage Regulators - Linear family. It offers several features such as low quiescent current, adjustable output voltage, thermal protection and current over-limit protection. It is an excellent choice for use in portable devices, since it is designed for high input voltage operation with low quiescent current. The device operates on the principle of linear voltage regulation, constantly monitoring and adjusting the output voltage to the desired value.
