LM4030AMF-2.5/NOPB

Overview

The LM4030AMF-2.5/NOPB is an ultra-high-precision shunt voltage reference manufactured by Texas Instruments, housed in a SOT-23-5 surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.05% and a temperature coefficient of 30 ppm/°C. The device supports a maximum shunt current of 50 mA and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Ultra-high precision performance with 0.05% initial accuracy
• Low temperature drift of 30 ppm/°C for stable operation
• Compact SOT-23-5 surface-mount packaging

Applications

• Precision data acquisition systems
• Portable instrumentation requiring low power
• Battery-powered measurement devices

Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS status as documented. Confirm the '-2.5' designation matches the required 2.5 V output voltage. Ensure the SOT-23-5 footprint aligns with the target PCB layout. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and revision history before procurement.

Selection Notes

Select this component when high accuracy and low temperature drift are critical requirements. The 50 mA maximum shunt current allows for moderate load driving capabilities compared to micropower alternatives. The wide operating temperature range makes it suitable for industrial environments. Consider the SOT-23-5 package size constraints during board design.

Part Context

This device belongs to the LM4030 series of shunt voltage references from Texas Instruments. It is designed to replace older discrete zener diode solutions in applications demanding superior stability and accuracy. The series offers various fixed voltage options within the same compact package family.

Replacement Considerations
