ADM7172ACPZ-5.0-R7 Application Field and Working Principle

ADM7172ACPZ-5.0-R7 is a linear voltage regulator from Analog Devices. It is a popular voltage regulator in the field of Power Management and Integrated Circuits (PMIC), which includes voltage regulators, linear regulators, switching regulators and other power solutions.The ADM7172ACPZ-5.0-R7 is a medium voltage drop linear regulator designed specifically for applications in the industrial, automotive, instrumentation, medical and avionics markets, as well as other applications requiring low dropout, low noise, and high accuracy performance. The output voltage accuracy range of this voltage regulator is 2.5 V to 5.5 V, making it a perfect choice for many applications.The ADM7172ACPZ-5.0-R7 linear regulator features an innovative architecture that provides high accuracy, low noise, and low dropout performance. It is based on a voltage divider topology, which allows it to optimize its performance based on input and output voltages. This makes it ideal for applications requiring low noise and high accuracy voltage regulation. Additionally, its low dropout voltage of 40 mV makes it suitable for applications where high efficiency is required.In addition to its low power consumption, the linear regulator\'s thermal protection temperature limit is 165°C (Tj), which is suitable for high temperature applications. It also features wide input supply range from 4.5 V to 18 V, overcurrent and overtemperature protection, and undervoltage lockout for improved power management.The ADM7172ACPZ-5.0-R7 is designed to be easy to use, allowing it to integrate easily with other components in a design. Its features, together with its wide input range and low power consumption, make it suitable for a range of applications.The ADM7172ACPZ-5.0-R7 employs a feedback loop configuration to maintain the output voltage at its programmed value. This feedback loop consists of three parts: reference voltage, error amplifier, and driver. The reference voltage is used to compare the output voltage with the programmed output voltage selected by the user. The error amplifier monitors the output voltage and the reference voltage and adjusts the output voltage to the programmed voltage by controlling the gate drive on the driver. This ensures that the output voltage remains constant no matter what the input voltage is.By using this feedback loop configuration, the ADM7172ACPZ-5.0-R7 is able to ensure high accuracy, low noise and low power consumption. Additionally, with its high temperature limit and wide range of input voltages, it is suitable for use in a variety of applications, such as industrial, automotive, and avionics.
