LM4041BIX3-1.2-T

Overview

The LM4041BIX3-1.2-T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown voltage of 1.225V with an initial accuracy of 0.2% at +25°C and a maximum temperature coefficient of 100ppm/°C. The device operates within a wide current range from 60µA to 12mA, ensuring stable performance across varying conditions. It features low dynamic impedance and output noise of 20µVRMS (10Hz to 10kHz). Packaged in the subminiature 3-pin SC70 surface-mount format, it is designed for space-critical applications and does not require external stabilizing capacitors.

Feature Summary

Ultra-small 3-pin SC70 package design
High precision with 0.2% initial accuracy
Capacitive load tolerant without external capacitors

Applications

Portable battery-powered equipment
Notebook computers
Cell phones
Industrial process controls

Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging as specified in official documentation. Confirm the 'IX3' designation matches the required SC70-3 package type. Ensure the 'B' grade aligns with the necessary 0.2% accuracy specifications for your circuit requirements before finalizing procurement.

Selection Notes

Select this component when space constraints necessitate the SC70-3 package over larger alternatives like SOT23-3. Choose this specific grade if a 0.2% initial accuracy meets system tolerances while balancing cost against higher precision options. Verify that the operating environment remains within the -40°C to +85°C range defined for the '_I_' suffix variant.

Part Context

This part belongs to the LM4041 family of improved precision micropower shunt voltage references. It utilizes bandgap principles to maintain a stable 1.225V output. The family includes variants with different accuracies (0.1%, 0.5%, 1%) and packages (SOT23-3), allowing designers to optimize for size, precision, or temperature range based on specific application needs.
