Overview
The ADM7172ACPZ-4.2-R7 is a high accuracy, low dropout regulator from Analog Devices Inc. It is designed to provide a regulated output voltage with a 4.2V fixed output. The device is designed to offer best-in-class transient response, load regulation, and getting to a stable output quickly.
Technical Features
The ADM7172ACPZ-4.2-R7 features a maximum dropout voltage of 200mV, allowing it to operate with very small headroom voltage. It also offers a low dropout voltage of 75mV at 1A output, reducing power dissipation and improving efficiency. The device is capable of sourcing up to 1A of output current and has a low 80μA quiescent current, making it suitable for battery-powered applications. It offers high PSRR (power supply rejection ratio) and excellent line and load transient response, making it ideal for noise-sensitive applications.
Application Scenarios
The ADM7172ACPZ-4.2-R7 is well-suited for a wide range of applications including portable and battery-powered equipment, instrumentation and measurement systems, data acquisition systems, and other noise-sensitive applications. Its high accuracy and low dropout features make it particularly suitable for applications that require a stable and regulated power supply with minimal power dissipation.
