LM4128BMF-2.5/NOPB

Voltage Reference Overview

The LM4128BMF-2.5/NOPB is a precision micropower 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 0.2%. The device operates within a temperature range of -40°C to +125°C and features a maximum shunt current of 20 mA. It supports a maximum series input voltage of 6 V and consumes a typical quiescent current of 60 µA.

Voltage Reference Feature Summary

Provides stable reference voltage with high initial accuracy
Operates efficiently at low power consumption levels
Designed for reliable performance across extended industrial temperature ranges

Voltage Reference Applications

Portable instrumentation requiring precise voltage standards
Battery-powered measurement systems
Data acquisition circuits needing stable reference sources

Voltage Reference Procurement Notes

Verify the complete part number including suffixes such as NOPB to ensure lead-free compliance and specific packaging options. Confirm that the SOT-23-5 footprint matches your PCB design constraints. Check for automotive qualification requirements if deploying in vehicle environments, as standard versions differ from AEC-Q100 qualified variants.

Voltage Reference Selection Notes

Select this component when a compact, low-power shunt reference is required for general-purpose applications. Ensure the input voltage remains below the 6 V maximum limit. Consider higher accuracy grades or automotive qualifications if operating conditions demand stricter tolerances or enhanced reliability standards beyond standard commercial specifications.

Voltage Reference Part Context

This device belongs to the LM4128 family of precision micropower shunt voltage references. The family offers various fixed output voltages and accuracy grades. The BMF variant specifically denotes a 0.2% initial accuracy level. The NOPB suffix indicates a lead-free and RoHS-compliant manufacturing process suitable for modern environmental regulations.
