Power Management Integrated Circuit (PMIC) refers to an integrated circuit with multiple power management functions integrated in one package, thereby saving space and reduce voltage reference design complexity. It is widely used in mobile phones, tablets, wearables and other portable and intelligent devices. Voltage Reference is a type of PMIC that helps to provide consistent and stable reference voltages to the circuit, preventing against sudden voltage drops. The ADR370ART-R2 voltage reference is an excellent example, designed to regulate the system voltage and improve system accuracy.The ADR370ART-R2 is a high-performance Precision Voltage Reference Module, ideal for space-constrained applications. It is particularly suitable for Linear Regulator, Voltage Comparator, Peak Detector and Shift Register, as well as other precision voltage reference applications. It features an operating temperature range of 0°C to 85°C, and a maximum output voltage of 1.22V. It also offers improved stability over a wide temperature range, thanks to its on-chip temperature-compensation circuit.The ADR370ART-R2 is composed of a high accuracy bandgap reference, a temperature compensation circuit, an external resistor and a feedback operational amplifier. The voltage reference output is set with an external resistor, with the amplifier then providing the output signal. The bandgap provides a constant voltage, and the compensation circuit eliminates the temperature drift. The configuration also eliminates the need for an external voltage divider and provides an improved output accuracy over a wide temperature range.The ADR370ART-R2 delivers high precision and noise immunity performance, thanks to a low quiescent current of 30 μA and high accuracy of 0.05%. Its shutdown input offers a flag to turn off the output, preventing any unnecessary power consumption. The input range is 2.7V to 6V and the device supports a maximum current of 10mA.In summary, the ADR370ART-R2 precision voltage reference module is ideal for use with linear regulators, voltage comparators, peak detectors and shift registers. It offers precise and stable voltage reference, eliminating the need for an external voltage divider, as well as improved stability over a wide temperature range. Its fuel efficiency and high accuracy make it the ideal choice for a variety of applications, from mobile phones and tablets, to wearables and other portable devices.
