LM4125AIM5X-2.5/NOPB

Voltage Reference Overview

The LM4125AIM5X-2.5/NOPB is a series voltage reference IC manufactured by Texas Instruments, featuring a fixed output voltage of 2.5V with an initial accuracy of ±0.2%. It operates within a supply voltage range of 2.7V to 40V and supports a maximum shunt current of 5mA. The device functions reliably across a temperature range from -40°C to +85°C. Packaged in a SOT-23-5 surface-mount format, it offers low noise performance suitable for precision analog applications requiring stable voltage references.

Voltage Reference Feature Summary

• Fixed 2.5V output voltage with high initial accuracy
• Low noise operation for precision signal conditioning
• Wide operating supply voltage range up to 40V

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'X' indicates tape-and-reel packaging configuration when sourcing components. Confirm that the 'NOPB' designation ensures lead-free compliance and RoHS standards are met according to manufacturer specifications. Cross-reference the full part number against official distributor catalogs to ensure correct package variant availability.

Voltage Reference Selection Notes

Select this component when a fixed 2.5V reference is required with tight initial accuracy tolerances. Consider the SOT-23-5 footprint for space-constrained designs. Ensure the application current draw remains within the 5mA limit and the input voltage stays above the minimum dropout requirement for proper regulation.

Voltage Reference Part Context

This part belongs to the LM4125 family of series voltage references designed for high-precision applications. It complements other Texas Instruments reference solutions by offering a fixed voltage option in a compact surface-mount package. The family targets industries requiring stable reference voltages for analog-to-digital conversion and sensor interfacing.

Voltage Reference Replacement Considerations

The LM4125AIM5-2.5/NOPB serves as a direct substitute, differing primarily in packaging format rather than electrical characteristics. Verify pinout compatibility and thermal performance when transitioning between reel and cut-tape variants.
