LM4128CMF-1.8

Voltage Reference Overview

The LM4128CMF-1.8 is a micropower series voltage reference manufactured by Texas Instruments, housed in a SOT-23-5 surface-mount package. It provides a fixed output voltage of 1.8 V with an initial accuracy of ±0.5%. The device features a temperature coefficient of 100 ppm/°C and operates within an input voltage range of 3.7 V to 5.5 V. It supports a maximum shunt current of 20 mA while consuming only 60 µA of supply current. The component functions reliably across a temperature range from -40°C to +125°C.

Voltage Reference Feature Summary

Delivers a stable 1.8 V reference voltage with ±0.5% initial accuracy for precision applications.
Operates with low power consumption of 60 µA, suitable for battery-powered systems.
Supports up to 20 mA load current capability within the specified input voltage range.

Voltage Reference Applications

Voltage Reference Procurement Notes

Verify the specific suffix against official documentation to confirm pinout compatibility and tolerance grades. Ensure the ordering part number matches the required accuracy and package type. Confirm RoHS compliance status through the manufacturer's latest datasheet or product information page before procurement.

Voltage Reference Selection Notes

Select this component when a fixed 1.8 V reference is required in a compact SOT-23-5 footprint. Consider the 100 ppm/°C temperature coefficient for thermal stability requirements. Evaluate the 60 µA quiescent current against system power budgets and verify the 20 mA shunt current capability meets load demands.

Voltage Reference Part Context

This device belongs to the LM4128 family of micropower series voltage references. It shares functional characteristics with other variants in the series, differing primarily in output voltage, accuracy grade, and package options. The CMF designation indicates a specific manufacturing lot and tolerance class within the standard commercial grade lineup.
