ADR365AUJZ-REEL7

Overview

The ADR365AUJZ-REEL7 is a precision band gap voltage reference providing a nominal 5.000 V output in a compact TSOT-23-5 package. It features an initial accuracy of ±8 mV and a temperature coefficient of 25 ppm/°C across the -40°C to +125°C range. The device operates with a quiescent current of 190 µA maximum and supports sourcing up to 5 mA while sinking up to 1 mA. It requires no external capacitors for stability, offers ultralow noise of 12.8 µV p-p (0.1 Hz to 10 Hz), and maintains a low dropout voltage of 300 mV.

Feature Summary

• Provides stable 5.000 V output using proprietary temperature drift curvature correction techniques.
• Eliminates the need for external input or output capacitors, reducing board space and system cost.
• Features bidirectional output capability allowing both sourcing and sinking of load currents.
• Delivers ultralow output voltage noise suitable for high-precision signal conditioning applications.

Applications

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

Procurement Notes

Verify the specific grade suffix against the datasheet ordering guide to confirm the exact temperature coefficient and accuracy class. Ensure the input supply voltage remains within the specified 5.3 V to 15 V range to maintain regulation. Confirm thermal management requirements are met given the package's thermal resistance characteristics during operation.

Selection Notes

Select this component when a fixed 5 V reference is required in space-constrained designs. It is suitable for applications needing simultaneous sourcing and sinking capabilities without external buffering. Consider the 25 ppm/°C drift specification against stricter B-grade alternatives if higher precision is necessary.

Part Context

This part belongs to the ADR36x family of micropower, low dropout voltage references manufactured by Analog Devices. The family includes variants with different output voltages and grades, all sharing the same compact TSOT package architecture and capacitor-free design philosophy for ease of integration.

FAQ

Does the ADR365AUJZ-REEL7 require an output capacitor for stability?

No, the device does not require an output capacitor for stability under any load condition, although one may be added to filter noise.

What is the minimum input voltage required for proper regulation?

The minimum input voltage is 5.3 V, which accounts for the 300 mV dropout voltage above the 5.000 V output.
