ADR366BUJZ-REEL7

Overview

The ADR366BUJZ-REEL7 is a micropower, low dropout voltage reference providing a fixed 3.300 V output in a compact TSOT-23-5 package. It features a B-grade temperature coefficient of 9 ppm/°C and an initial accuracy of ±4 mV (±0.125%). The device operates with a quiescent current of 190 µA maximum and supports sourcing up to 5 mA and sinking 1 mA. It requires no external capacitors for stability, offers ultralow noise of 9.3 µV p-p (0.1 Hz to 10 Hz), and functions within a supply range of 3.6 V to 15 V across temperatures from -40°C to +125°C.

Feature Summary

• Proprietary temperature drift curvature correction techniques achieve low temperature drift in 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 REEL7 indicates reel packaging when confirming order details. Ensure the B grade designation matches the required 9 ppm/°C temperature coefficient and ±4 mV accuracy specifications. Confirm the TSOT-23-5 package type aligns with PCB layout requirements. Cross-reference the manufacturer part number against official Analog Devices documentation to validate revision status.

Selection Notes

Select this component for applications requiring a stable 3.3 V reference with minimal power consumption. The low dropout voltage allows operation close to the output level. Consider the sink/source capability for flexible circuit interfacing. Verify that the 190 µA quiescent current fits the battery life constraints of the target portable device.

Part Context

This part belongs to the ADR360/ADR361/ADR363/ADR364/ADR365/ADR366 family of precision band gap voltage references. These devices share common architectural features including micropower operation and capacitor-free stability. The ADR366 specifically provides a 3.300 V output option within this series, distinguished by its specific grading and package configuration.

Replacement Considerations

Other members of the ADR36x family offer different output voltages or grades. Verify if alternative voltage levels or temperature coefficients are acceptable substitutes based on specific circuit requirements.
