PMIC voltage references are capable of providing a constant voltage output over varying current and temperature conditions. ADR02BR is a precision bandgap voltage reference designed for use in a single-supply 3.3 V or 5 V systems and provides circuits with precision, low-noise and low-temperature drift reference voltages. This device is optimized for operation from -40°C to +125°C.

The core of the ADR02BR voltage reference is an advanced and ultra low-power bandgap reference specifically designed for micro-power applications. The bandgap reference voltage is held to within 0.3% of the nominal voltage by an advanced trimming technique. This enables the ADR02BR to provide higher accuracy reference applications for components such as analog-to-digital converters, sample and hold circuits, and voltage regulators.

The ADR02BR has a wide working temperature range, allowing the reference to be used in a wide variety of high-temperature applications. The device is designed to provide a stable and high accuracy voltage reference even in the presence of temperature changes. This means that the device can maintain a steady output despite continuous exposure to extreme temperatures.

The ADR02BR has a low output noise voltage, making it ideal for applications that require a high degree of accuracy and stability. The low noise voltage enables an improved dynamic accuracy in the reference voltage output. This helps improve the accuracy and the stability of analog-to-digital converters and voltage regulators.

The ADR02BR also has a low quiescent current consumption, making it suitable for battery-powered applications. The low quiescent current consumption is made possible by an internal voltage regulator that limits the current consumption to a preset value. This helps ensure that the device can supply the same amount of power regardless of the circuit load.

The ADR02BR is also highly reliable and has an extended operating life. It is designed to operate without fail over a wide range of operating temperatures and currents. Its long life is further increased by the integration of a high-temperature polymer package, which helps protect the device from prolonged exposure to extreme temperatures.

In summary, the ADR02BR is a precision bandgap voltage reference which is optimized for use in a single-supply 3.3 V or 5 V systems. It has a wide working temperature range, a low output noise voltage, low quiescent current consumption, and a high-temperature polymer package for extended reliability and a long operational life. The device also has a precision trimming technique for high accuracy reference applications. This makes the ADR02BR an ideal choice for precision voltage reference applications in analog-to-digital converters, sample and hold circuits, and voltage regulators.
