LM4051BIM3-1.2+

Voltage Reference Overview

The LM4051BIM3-1.2+ is a precision micropower shunt voltage reference manufactured by Analog Devices under the Maxim Integrated brand. It provides a fixed output voltage of 1.225 V with an initial accuracy of 0.2%. The device operates within a temperature range of -40°C to +85°C and features a maximum shunt current of 12 mA. Packaged in a compact SOT-23-3 surface-mount format, it is designed for space-constrained applications requiring stable voltage regulation.

Voltage Reference Feature Summary

Eliminates the need for external stabilizing capacitors while maintaining stability with any capacitive load
Utilizes fuse and Zener-zap reverse breakdown voltage trim during wafer sort to ensure high precision
Offers low dynamic impedance for stable performance across wide operating temperatures and currents

Voltage Reference Applications

Battery-powered equipment
Data acquisition systems
Portable instruments

Voltage Reference Procurement Notes

Verify the manufacturer designation as Analog Devices Inc., formerly Maxim Integrated, to ensure component authenticity. Confirm the package type is SOT-23-3 and the output voltage is strictly 1.225 V. Check RoHS compliance status and ensure the operating temperature range matches the specific application requirements of -40°C to +85°C before procurement.

Voltage Reference Selection Notes

Select this component for designs requiring a sub-miniature footprint without external stabilization components. It is suitable for applications where low power consumption is critical, given its micropower characteristics. Ensure the circuit can handle the maximum shunt current of 12 mA and that the required accuracy aligns with the 0.2% initial tolerance specification.

Voltage Reference Part Context

This part belongs to the LM4051-N series of precision voltage references. It shares design similarities with other shunt references but is distinguished by its specific 1.225 V output and B-grade accuracy. The component is widely used in industrial and consumer electronics where precise voltage regulation in small packages is essential.
