LM4040BIX3-3.0+T

Overview

The LM4040BIX3-3.0+T is a precision, two-terminal shunt mode bandgap voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse-breakdown output voltage of 3.000V with an initial accuracy of 0.2%. The device features a maximum temperature coefficient of 100ppm/°C and operates within a temperature range of -40°C to +85°C. It utilizes a subminiature 3-pin SC70 surface-mount package (1.8mm x 1.8mm) and supports a shunt current capability ranging from 60μA to 15mA.

Feature Summary

• Ultra-small 3-pin SC70 package designed for space-critical applications
• Laser-trimmed resistors ensure precise initial accuracy
• Stable operation without requiring external stabilizing capacitors
• Capable of tolerating any capacitive load

Applications

• Portable, battery-powered equipment
• Notebook computers
• Cell phones
• Industrial process controls
• Automotive systems

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type, accuracy grade, and temperature range. Ensure the component matches the required electrical specifications for the target application before procurement.

Selection Notes

Select this component when a compact footprint is required alongside high precision. The 0.2% accuracy and low temperature coefficient make it suitable for demanding measurement circuits. Verify that the operating current remains within the specified 60μA to 15mA range for optimal performance.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. The 'B' designation indicates a 0.2% initial accuracy grade, while the 'IX3' suffix specifies the SC70 package and industrial temperature range. It serves as a stable reference source in power management and signal conditioning circuits.

Replacement Considerations

LM4040AIM3-3.0+T offers higher 0.1% accuracy. LM4040CIM3-3.0+T provides 0.5% accuracy. LM4040BIM3-3.0+T uses the SOT23-3 package instead of SC70.
