LM4050AIM3X-5.0/NOPB

Voltage Reference Overview

The LM4050AIM3X-5.0/NOPB is a micropower shunt precision voltage reference manufactured by Texas Instruments, housed in an SOT-23-3 surface-mount package. It provides a fixed output voltage of 5 V with an initial accuracy of 0.1% and a temperature coefficient of 50 PPM/°C. The device supports a maximum shunt current of 15 mA and operates within a temperature range of -40°C to +125°C.

Voltage Reference Feature Summary

• Provides high-precision voltage referencing with 0.1% initial accuracy for sensitive measurement applications.
• Operates over an extended industrial temperature range from -40°C to +125°C.
• Features low power consumption suitable for battery-powered or energy-efficient designs.

Voltage Reference Applications

• Portable instrumentation requiring stable voltage references
• Data acquisition systems needing precise analog-to-digital conversion references
• Battery-operated equipment where low quiescent current is critical

Voltage Reference Procurement Notes

Verify the specific suffix 'A' indicates the 0.1% accuracy grade and 'IM3X' denotes the SOT-23-3 reel packaging. Confirm RoHS compliance status as detailed in the official datasheet. Ensure the operating environment stays within the specified -40°C to +125°C thermal limits for reliable performance.

Voltage Reference Selection Notes

Select this component when a fixed 5 V reference with tight tolerance (0.1%) is required in a compact SOT-23-3 footprint. It is suitable for applications demanding low noise and stability across wide temperature variations. Compare against lower accuracy grades if cost sensitivity outweighs precision requirements.

Voltage Reference Part Context

This part belongs to the LM4050-N series of micropower shunt voltage references from Texas Instruments. The series offers various output voltages and accuracy grades, all sharing a common low-power architecture and small form factor designed for space-constrained electronic designs.

Voltage Reference Replacement Considerations

Direct substitutes include other LM4050 variants with matching 5 V output and similar accuracy, such as LM4050BIM3X-5.0/NOPB (0.2% accuracy) or LM4050CEM3X-5.0/NOPB (0.5% accuracy), provided the looser tolerance meets design specifications.
