LM4040BIX3-2.1-T

Overview

The LM4040BIX3-2.1-T is a micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated, featuring a fixed output of 2.1V with 0.2% initial accuracy and a temperature coefficient of 100 ppm/°C. It operates within a current range of 60 µA to 15 mA across an industrial temperature span of -40°C to +85°C. Housed in a compact SOT-23-3 surface-mount package, this device provides stable precision for space-constrained designs requiring low power consumption.

Feature Summary

Provides high-precision voltage regulation with 0.2% initial accuracy
Operates efficiently at ultra-low quiescent currents suitable for battery-powered systems
Maintains stability across the full industrial temperature range

Applications

Portable instrumentation circuits
Battery-powered measurement devices
Data acquisition systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability upon receipt. Ensure storage conditions align with moisture sensitivity level requirements to prevent package damage during soldering processes.

Selection Notes

Select this component when precise 2.1V reference is required in minimal footprint applications. The SOT-23-3 package suits dense PCB layouts. Verify that the 100 ppm/°C temperature coefficient meets system thermal drift specifications and that the 15 mA maximum shunt current accommodates load variations without exceeding power dissipation limits.

Part Context

This part belongs to the LM4040 family of improved precision micropower shunt references. The 'B' suffix denotes 0.2% accuracy, while 'IX3' indicates the SC-70-3 package variant. It serves as a compact alternative to larger packages like SOT-23-3L or TO-92, offering similar electrical performance in a smaller form factor for modern electronics.
