LM4132CQ1MFT3.0

Voltage Reference Overview

The LM4132CQ1MFT3.0 is an automotive-grade precision series voltage reference from Texas Instruments, housed in a SOT-23-5 package. It provides a fixed output of 3.0V with an initial accuracy of ±0.2%. The device operates within a temperature range of -40°C to +125°C and features a temperature coefficient of 30 ppm/°C. It supports a maximum input voltage of 5.5V and can deliver up to 20mA of output current while consuming approximately 60µA of supply current. The component is AEC-Q100 qualified for automotive applications.

Voltage Reference Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Precision series regulation architecture for stable output
• Low power consumption suitable for battery-operated systems
• Compact surface-mount packaging for space-constrained designs

Voltage Reference Applications

• Automotive sensor signal conditioning circuits
• Data acquisition systems requiring high stability
• Portable instrumentation powered by single supplies
• Microcontroller analog-to-digital converter references

Voltage Reference Procurement Notes

Verify the specific suffix 'MFT' indicates tape-and-reel packaging when ordering. Confirm the 'Q1' designation aligns with required automotive reliability standards for your application. Ensure the 3.0V output variant matches the system design requirements before procurement. Check for RoHS compliance status as indicated in official documentation.

Voltage Reference Selection Notes

Select this component when a fixed 3.0V reference with ±0.2% accuracy is required in a small SOT-23-5 footprint. It is suitable for designs needing AEC-Q100 qualification without sacrificing precision. Consider the 30 ppm/°C temperature coefficient against environmental operating ranges. Compare against non-automotive grades if cost is a primary driver but automotive reliability is not mandated.

Voltage Reference Part Context

This part belongs to the LM4132 family of low-dropout precision voltage references. The LM4132 series offers various output voltages and accuracy grades. The Q1 suffix specifically denotes automotive-grade processing and testing. The MFT suffix typically indicates reel packaging for automated assembly processes.

Voltage Reference Replacement Considerations

LM4132CQ1MFT3.3/NOPB: Same package and grade but 3.3V output. LM4132EMF-3.0/NOPB: Non-automotive grade with similar electrical characteristics. LM4132AMFX-3.0/NOPB: Higher accuracy (0.05%) but non-automotive grade.
