LM4051CEM3-1.2/NOPB

Voltage Reference Overview

The LM4051CEM3-1.2/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 1.225 V with an initial accuracy of ±0.5%. The device operates within a temperature range of -40°C to +85°C and features a low temperature coefficient of 50 ppm/°C. It is housed in a compact SOT-23-3 surface-mount package, suitable for space-constrained designs requiring stable voltage references.

Voltage Reference Feature Summary

Provides a fixed 1.225 V output with high precision
Operates over an extended industrial temperature range
Utilizes a compact three-pin SOT-23 package

Voltage Reference Applications

Portable battery-powered instrumentation
Data acquisition systems
Microcontroller power supply monitoring

Voltage Reference Procurement Notes

Verify the specific suffix 'CEM3' corresponds to the commercial temperature grade (-40°C to +85°C) and SOT-23-3 package variant. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance as per current manufacturer specifications before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a fixed 1.225 V reference is required in a small footprint. Ensure the application current does not exceed the maximum shunt current rating. Compare against the AIM3 series if higher accuracy or wider temperature ranges are necessary for the specific design constraints.

Voltage Reference Part Context

This part belongs to the LM4051 family of micropower shunt voltage references from Texas Instruments. It shares functional similarities with other members like the LM4050 series but offers a lower fixed voltage option. The device is designed to replace older zener diode references in applications demanding better stability and lower noise.
