LM4040DEM3-3.0+T

Overview

The LM4040DEM3-3.0+T is a precision, two-terminal shunt mode bandgap voltage reference with a fixed reverse-breakdown voltage of 3.000V. It features an initial accuracy of 1.0% and a maximum temperature coefficient of 150ppm/°C. The device operates within a wide current range of 60μA to 15mA and supports an extended temperature range from -40°C to +125°C. Packaged in the subminiature 3-pin SC70 surface-mount format, it offers low dynamic impedance and stable performance without requiring external stabilizing capacitors.

Feature Summary

Ultra-small 3-pin SC70 package for space-critical applications
Laser-trimmed resistors ensure precise initial accuracy
Stable operation over a wide operating current range
No output capacitors required for frequency stability

Applications

Portable, Battery-Powered Equipment
Notebook Computers
Cell Phones
Industrial Process Controls
Automotive

Procurement Notes

Verify the specific suffix '+T' indicates tape and reel packaging and '+' denotes lead-free/RoHS compliance. Confirm the 'DEM3' designation corresponds to the D grade (1.0% accuracy), E temp range (-40°C to +125°C), M3 package code (SOT23) or X3 (SC70) as per the ordering table. Ensure the source document explicitly links this exact part number to the SC70 package variant if that form factor is required, as M3 typically denotes SOT23 in Maxim nomenclature; cross-reference the ordering information table carefully.

Selection Notes

Select this component when a 3.000V reference with 1.0% tolerance is sufficient for the application. The extended temperature rating makes it suitable for automotive or industrial environments. Consider the SC70 package size if board real estate is limited compared to standard SOT23 options. Ensure the circuit design maintains shunt current between 60μA and 15mA for optimal regulation and noise performance.

Part Context

This device belongs to the LM4040 family of improved precision micropower shunt voltage references. The family provides multiple fixed reverse-breakdown voltages including 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Variants are available in both SOT23 and SC70 packages with different accuracy grades ranging from 0.1% to 1.0%.
