LM4050AIM3X-2.5

Voltage Reference Overview

The LM4050AIM3X-2.5 is a precision micropower shunt voltage reference manufactured by Texas Instruments, formerly National Semiconductor. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.1% and a temperature coefficient of 50 ppm/°C. The device operates within a wide current range of 60 µA to 15 mA and functions across a temperature range of -40°C to +125°C. It is housed in a compact SOT-23-3 surface-mount package.

Voltage Reference Feature Summary

Provides high-precision voltage referencing with laser-trimmed resistors for excellent initial accuracy.
Operates as a two-terminal shunt-mode device without requiring external stabilizing capacitors.
Features low dynamic impedance to maintain stable reverse breakdown voltage accuracy over varying currents.

Voltage Reference Applications

Space-critical applications utilizing subminiature packages
Portable battery-powered equipment requiring low quiescent current
Data acquisition systems needing stable reference voltages

Voltage Reference Procurement Notes

Verify the manufacturer designation, as National Semiconductor was acquired by Texas Instruments. Confirm the specific suffix 'NOPB' if lead-free compliance is required. Ensure the ordering part number matches the exact voltage and tolerance grade needed for the design.

Voltage Reference Selection Notes

Select this component when a fixed 2.5 V reference with ±0.1% accuracy is required in a small footprint. It is suitable for designs needing stability without external compensation capacitors. Consider the 50 ppm/°C temperature coefficient for thermal environment constraints.

Voltage Reference Part Context

This part belongs to the LM4050/LM4051 family of precision micropower shunt voltage references. These devices are available in multiple fixed reverse breakdown voltages and offer three grades of initial accuracy. They are designed for applications where space and power consumption are critical constraints.
