Voltage Reference datasheet and documents for LM4128DMF-3.0/NOPB

LM4128DMF-3.0/NOPB

Voltage Reference Overview

The LM4128DMF-3.0/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring a fixed output of 3 V with an initial accuracy of 0.2%. It operates within a temperature range of -40°C to +125°C and exhibits a temperature coefficient of 100 ppm/°C. The device supports a maximum input voltage of 6 V and a maximum shunt current of 20 mA, while consuming only 60 µA of operating supply current. Packaged in a compact SOT-23-5 surface-mount format, it is designed for applications requiring stable reference voltages under low power constraints.

Voltage Reference Feature Summary

Provides a stable 3 V reference voltage with high initial accuracy
Operates efficiently with ultra-low quiescent current consumption
Maintains performance across extended industrial temperature ranges

Voltage Reference Applications

Portable battery-powered instrumentation
Data acquisition systems
Microcontroller analog-to-digital converter references

Voltage Reference Procurement Notes

Verify the specific suffix DMF against official datasheets to confirm package type and tolerance grade. Ensure compatibility with system thermal requirements given the SOT-23-5 footprint. Confirm RoHS compliance status through manufacturer documentation before integration into regulated assemblies.

Voltage Reference Selection Notes

Select this component when a 3 V precision reference is required with minimal power draw. Compare initial accuracy and temperature coefficients against alternative series references if tighter stability is needed. Verify that the 20 mA shunt current limit meets the load requirements of the target circuit design.

Voltage Reference Part Context

This part belongs to the LM4128 family of micropower series voltage references from Texas Instruments. It shares architectural similarities with other variants in the series but differs in output voltage and accuracy grades. The family is designed for space-constrained applications requiring reliable voltage regulation without significant power overhead.
