ADR366AUJZ-R2

Overview

The ADR366AUJZ-R2 is a micropower, low dropout voltage reference providing a fixed 3.3 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 an output sourcing current of 5 mA and sinking current of -1 mA. It functions within a supply voltage range of 3.6 V to 15 V and operates across a temperature range of -40°C to +125°C.

Feature Summary

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

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeits. Confirm the specific B-grade performance parameters match application requirements. Check for end-of-life status or discontinuance notices from Analog Devices prior to finalizing procurement plans.

Selection Notes

Select this component when a stable 3.3 V reference is required in space-constrained designs. Ensure the input voltage remains at least 300 mV above the output voltage to maintain regulation. Consider the 190 µA quiescent current impact on total system power consumption for battery-operated applications.

Part Context

This part belongs to the ADR36x family of precision 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, 3.000 V, 4.096 V, and 5.000 V. All members share similar low-power characteristics and the TSOT package form factor.
