ADR127AUJZ-R2

Overview

The ADR127AUJZ-R2 is a micropower, high precision series mode band gap voltage reference with source and sink capability. It provides a nominal output voltage of 1.25 V with an initial accuracy of ±0.24% (A Grade) and a maximum temperature coefficient of 25 ppm/°C. The device operates within an input range of 2.7 V to 18 V and requires a dropout voltage of 1.45 V. Quiescent current is typically 85 μA. It supports load currents up to +5 mA sourcing and -2 mA sinking. The component is housed in a 6-lead TSOT (UJ-6) package and functions across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

Patented temperature-drift curvature correction technique minimizes nonlinearities in the output voltage versus temperature characteristics.
Low dropout performance allows stable operation with minimal headroom above the nominal output voltage.
Integrated source and sink capability enables flexible interface configurations for various load requirements.

Applications

Battery-powered instrumentation
Portable medical equipment
Data acquisition systems

Procurement Notes

Verify the specific grade and packaging configuration against project requirements before procurement. Confirm that the input voltage supply remains within the specified 2.7 V to 18 V range to ensure proper regulation. Ensure thermal management accounts for the power dissipation limits inherent to the TSOT package under varying ambient temperatures and load conditions.

Selection Notes

Select this component when low quiescent current and high precision are required in space-constrained designs. The ADR127 variant is specifically suited for applications needing a 1.25 V reference with a wider input voltage range compared to lower voltage counterparts. Consider the ±0.24% initial accuracy and 25 ppm/°C temperature coefficient for high-resolution data conversion circuits.

Part Context

This part belongs to the ADR12x family of micropower LDO voltage references manufactured by Analog Devices Inc. The family includes variants with different nominal output voltages, such as the ADR121 (2.5 V) and ADR125 (5.0 V), all sharing similar architectural features and package options. These devices utilize a series mode band gap reference architecture optimized for low power consumption.
