ADP1712AUJZ-1.0-R7 application field and working principle
The ADP1712AUJZ-1.0-R7 is a programmable, low-dropout, low-quiescent current linear voltage regulator from Analog Devices’ ADP1712 family of feature-rich linear voltage regulators. This LDO regulator is a high-accuracy, low-dropout device that provides excellent regulation in typical applications as low as 1.2V and ensures stable operation over a variety of load conditions. It is well suited for both medium- and high-accuracy requirements and is available in a 14-pin SOIC package.The ADP1712 family of voltage regulators features a wide range of input and output voltages, which enables them to be used in a wide variety of applications. The ADP1712AUJZ-1.0-R7 has an adjustable range of 0.8V to 5.5V (in 0.1V increments) with a maximum of 5.5V, making it ideal for applications requiring 0.8V to 5.5V outputs.The ADP1712AUJZ-1.0-R7 offers excellent load regulation, line regulation and transient response. The device also features a programmable current limit and thermal protection for improved system reliability. In addition, the device includes an on-chip control loop compensation that allows for external tuning and optimization of loop dynamics and stability for a given design.The device has four main components: an error amplifier, an on-chip reference, a pass transistor, and a current limit set resistor. The programmable voltage reference sets the output voltage while the error amplifier senses and compares the input and output voltages, creating an error signal, which is converted to current through the pass transistor. As the output voltage increases, the transistor current decreases, driving the output voltage back to the desired level. The current limit set resistor allows the user to externally set the maximum current the device will attempt to draw, making it suitable for a variety of applications.In conclusion, the ADP1712AUJZ-1.0-R7 is a feature-rich, low-quiescent current linear voltage regulator from Analog Devices’ ADP1712 family of voltage regulators. It is well suited for both medium- and high-accuracy requirements and features a programmable current limit and thermal protection for improved system reliability. The device offers excellent load regulation, line regulation and transient response, and its adjustable voltage range makes it suitable for applications requiring 0.8V to 5.5V outputs.
