ADR361AUJZ-REEL7

Overview

The ADR361AUJZ-REEL7 is a precision band gap voltage reference providing a nominal output of 2.5 V in a compact TSOT-5 package. It operates with a maximum quiescent current of 190 µA and supports an input voltage range from 2.8 V to 15 V. The device features a low dropout voltage of 300 mV, allowing stable regulation with minimal supply headroom. It delivers up to 5 mA sourcing current and -1 mA sinking current without requiring external capacitors for stability.

Feature Summary

• Proprietary temperature drift curvature correction techniques achieve low temperature coefficients within a small footprint.
• Advanced internal design eliminates the need for external capacitors, reducing board space and system cost.
• Capable of both sourcing and sinking load currents while maintaining high precision and low noise performance.

Applications

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

Procurement Notes

Verify the specific grade suffix (e.g., AUJZ) against the manufacturer's ordering guide to confirm initial accuracy and temperature coefficient specifications. Ensure the input voltage supplied to the VIN pin remains within the 2.8 V to 15 V operational range to maintain specified line regulation and avoid exceeding absolute maximum ratings.

Selection Notes

Select this component when a stable 2.5 V reference is required in space-constrained designs. The absence of external capacitor requirements simplifies layout compared to traditional references. Consider the thermal resistance characteristics if operating near the upper limits of the junction temperature range under high load conditions.

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 fixed output voltages such as 2.048 V, 3.0 V, and 5.0 V, all sharing similar architectural benefits like ultralow noise and high precision in the TSOT package.

Replacement Considerations

Direct functional substitutes within the same family include the ADR360, ADR363, ADR364, ADR365, and ADR366 series devices. These share identical pinouts and packaging but provide different nominal output voltages. Verify that the alternative voltage level meets the circuit requirements before substitution.
