LM4050CIX3-2.5-T

Voltage Reference Overview

The LM4050CIX3-2.5-T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown voltage of 2.5V with an initial accuracy of 0.5% and a maximum temperature coefficient of 50ppm/°C. The device operates within a wide current range from 60µA to 15mA and functions reliably across temperatures from -40°C to +125°C. It utilizes a compact SC-70-3 surface-mount package.

Voltage Reference Feature Summary

• Ultra-small 3-pin SC-70 surface-mount package for space-critical applications
• Laser-trimmed resistors ensure excellent initial accuracy without external capacitors
• Wide operating current range ensures stable performance over varying loads

Voltage Reference Applications

• Portable battery-powered instrumentation
• Data acquisition systems
• Handheld meters

Voltage Reference Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the 'C' grade corresponds to the 0.5% initial accuracy specification. Ensure the SC-70-3 footprint matches the target PCB design constraints. Cross-reference the manufacturer part number with authorized distributors to confirm current production status.

Voltage Reference Selection Notes

Select this component when a 2.5V reference is required in a minimal footprint. The 0.5% accuracy suits general-purpose applications where tighter tolerances are unnecessary. Consider the 60µA minimum current requirement for low-power designs. Evaluate the 50ppm/°C drift against environmental temperature variations.

Voltage Reference Part Context

This part belongs to the LM4050/LM4051 family of two-terminal shunt references. The family offers multiple fixed voltages including 1.225V, 2.048V, 3.000V, and 5.000V. Variants exist in SOT-23 packages and different accuracy grades such as 0.1% and 0.25%.

Voltage Reference Replacement Considerations

LM4050CIX3-2.5+ serves as a direct tube-packaged alternative. LM4050DIM3-2.5+ offers the same electrical specifications in a SOT-23-3 package.
