LM4050CIM3X-2.5/NOPB

Voltage Reference Overview

The LM4050CIM3X-2.5/NOPB is a micropower shunt voltage reference from Texas Instruments, housed in a SOT-23-3 surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.5%. The device features a temperature coefficient of 50 ppm/°C and supports a maximum shunt current of 15 mA. It operates within an extended industrial temperature range of -40°C to +125°C.

Voltage Reference Feature Summary

• Provides stable precision voltage reference performance in a compact SOT-23-3 footprint
• Designed for low-power applications with micropower consumption characteristics
• Maintains specified accuracy across the full industrial operating temperature range

Voltage Reference Applications

• Portable battery-powered instrumentation systems
• Data acquisition and measurement circuits
• Handheld devices requiring precise voltage references

Voltage Reference Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status as indicated in official documentation. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly. Validate part markings against datasheet specifications to prevent counterfeit substitution.

Voltage Reference Selection Notes

Select this component when a 2.5 V reference with ±0.5% accuracy is required in a SOT-23-3 package. Consider the 50 ppm/°C temperature coefficient for thermal stability needs. Verify that the 15 mA maximum shunt current meets circuit load requirements. Ensure the -40°C to +125°C operating range aligns with environmental constraints.

Voltage Reference Part Context

This part belongs to the LM4050-N series of micropower shunt voltage references. It shares the same family architecture as variants with different output voltages and accuracies. The 'CIM3X' suffix indicates specific packaging and versioning within the Texas Instruments portfolio.

Voltage Reference Replacement Considerations

LM4050CEM3X-2.5/NOPB offers similar specifications with ±0.5% accuracy. LM4050AEM3X-2.5/NOPB provides higher precision at ±0.1% accuracy. Both are compatible pin-for-pin replacements within the same series.
