ADR363BUJZ-R2

Overview

The ADR363BUJZ-R2 is a micropower, low noise series voltage reference providing a fixed 3.000 V output in a compact TSOT-5 package. It features a B-grade temperature coefficient of 9 ppm/°C and an initial accuracy of ±3 mV. The device operates with a maximum quiescent current of 190 µA and supports a wide input voltage range from 3.3 V to 15 V. It delivers up to +5 mA sourcing and -1 mA sinking output current without requiring external capacitors for stability.

Feature Summary

• Proprietary curvature correction techniques achieve low temperature drift within a small footprint.
• Advanced design eliminates the need for external capacitors, reducing board space and system cost.
• Band gap architecture referenced to the output attenuates ground line noise effects.

Applications

• Battery-powered instruments
• Portable medical instruments
• Data acquisition systems
• Industrial process controls

Procurement Notes

Verify the specific suffix R2 indicates reel packaging when ordering. Confirm the B grade designation matches the required 9 ppm/°C temperature coefficient and ±3 mV accuracy specifications. Ensure the TSOT-5 package type aligns with the target PCB layout constraints.

Selection Notes

Select this component for applications requiring high precision in a minimal surface-mount footprint. The low dropout characteristic allows operation with supply voltages only slightly higher than the 3 V output. Consider the 190 µA quiescent current for battery life calculations in portable designs.

Part Context

This part belongs to the ADR36x family of band gap voltage references manufactured by Analog Devices. The family includes variants with different fixed output voltages such as 2.048 V, 2.500 V, 4.096 V, 5.000 V, and 3.300 V, all sharing similar low power and low noise characteristics.
