LM4050CIX3-3.0-T

Voltage Reference Overview

The LM4050CIX3-3.0-T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown output voltage of 3.0 V with an initial accuracy of 0.5%. The device features a maximum temperature coefficient of 50 ppm/°C and operates over a wide temperature range from -40°C to +125°C. It supports a shunt current range up to 15 mA and utilizes a compact SC-70-3 surface-mount package.

Voltage Reference Feature Summary

• Provides stable reference voltage without requiring external stabilizing capacitors
• Maintains accuracy across wide operating current ranges
• Designed for space-critical applications with ultra-small footprint

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'CIX3' against official manufacturer documentation to confirm pinout compatibility and exact electrical tolerances. Ensure the component matches the required SC-70-3 package dimensions and lead finish specifications before integration into production designs.

Voltage Reference Selection Notes

Select this component when a 3.0 V reference with 0.5% initial accuracy is required in a minimal footprint. Consider the 50 ppm/°C temperature coefficient for thermal stability needs. Verify that the 15 mA maximum shunt current meets the circuit load requirements.

Voltage Reference Part Context

This part belongs to the LM4050 series of two-terminal shunt voltage references. The series offers multiple fixed breakdown voltages and is characterized by low dynamic impedance and high precision, making it suitable for replacing larger packages like SOT-23 in compact designs.

Voltage Reference Replacement Considerations

Check for direct equivalents such as LM4050CIM3-3.0 if SOT-23 packaging is acceptable. Verify functional compatibility with TL4050 variants, noting potential differences in package type and noise specifications.
