The ADR444ARZ is an adjustable voltage reference in the PMIC (Power Management IC) family. It is an ideal, low-cost device for adjustable voltage references in many applications. It provides a reference voltage of 0.6V to 5.5V over a wide temperature range, making it suitable for a variety of configurations and outputs.

The ADR444ARZ is based on standard band gap architecture, where the laser trimmed resistors provide the stability, the current source provides the output stability and the operational amplifier maintains the accuracy of the reference voltage. The device has low initial accuracy and a very tight overall output voltage regulation of ± 0.02%. It also has very low current consumption of just 8 µA at 24V, making it suitable for low power applications.

The ADR444ARZ operates over a wide temperature range of -40°C to +85°C, making it highly suitable for industrial, automotive and avionic applications. The device also features excellent power supply rejection of up to 60 dB, thus providing stable operation under heavy load and supply variations. It also offers protection against reversed supply voltages, ESD protection and short-circuit protection.

The device is available in two package variants, namely a TO-252, four-pin configuration and a DIP (Dual InLine Package), four-pin configuration. This makes it highly suited for both surface mount and through-hole applications. Its standard pin configuration is a very convenient one, making it easy to use and cost effective. It also offers superior performance in both switching and linear applications.

In applications where an adjustable and accurate voltage reference is needed, the ADR444ARZ is a great choice. It can be used in many industrial, automotive and avionic applications that require a low power, low cost and highly accurate voltage reference solution. The device also offers superior performance in both switching and linear applications, making it a versatile component.
