LM4050CIX3-2.5

Voltage Reference Overview

The LM4050CIX3-2.5 is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown output voltage of 2.5V with an initial accuracy of 0.5%. The device features a maximum temperature coefficient of 50ppm/°C, guaranteed over an operating temperature range of -40°C to +125°C. It operates within a wide shunt current range from 60µA to 15mA and utilizes a subminiature SC-70 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
• No external stabilizing capacitor required while ensuring stability with any capacitive loads

Voltage Reference Applications

• Portable instrumentation
• Battery-powered systems
• Handheld meters

Voltage Reference Procurement Notes

Verify the specific suffix 'IX3' against official manufacturer documentation to confirm the exact package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your region. Confirm that the 0.5% accuracy grade aligns with your circuit design tolerances before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a compact footprint is required alongside stable voltage referencing in portable devices. The 60µA minimum operating current allows for efficient battery life extension compared to higher quiescent current alternatives. Verify that the 15mA maximum shunt current capability satisfies the load requirements of the target application circuit.

Voltage Reference Part Context

This part belongs to the LM4050/LM4051 family of precision two-terminal shunt-mode bandgap voltage references. The series offers multiple fixed reverse breakdown voltages including 1.225V, 2.048V, 3.000V, 3.3V, 4.096V, and 5.000V. The LM4050 variant specifically denotes the standard accuracy grades available in the product line.

Voltage Reference Replacement Considerations

Check for direct substitutes such as LM4050AIM3-2.5 or LM4050BIM3-2.5 if tighter accuracy grades are needed. Verify pinout compatibility with existing PCB layouts when considering alternative packages like SOT-23.
