LM4051BIM3-1.2-T

Voltage Reference Overview

The LM4051BIM3-1.2-T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown voltage of 1.225V with an initial accuracy of 0.2%. The device operates within a wide current range from 60µA to 15mA and features a maximum temperature coefficient of 50ppm/°C over the -40°C to +85°C industrial temperature range. Packaged in a compact SC-70 (SOT-323) surface-mount format, it eliminates the need for external output capacitors while tolerating capacitive loads.

Voltage Reference Feature Summary

Provides stable reference voltage without requiring external output capacitors
Maintains stability when connected to capacitive loads
Offers high initial accuracy with low temperature drift

Voltage Reference Applications

Portable battery-powered equipment
Notebook computers
Cell phones
Industrial process controls
Automotive systems

Voltage Reference Procurement Notes

Verify the specific suffix '-T' indicates tape-and-reel packaging configuration as per manufacturer documentation. Confirm that the 'B' grade designation corresponds to the 0.2% initial accuracy specification. Ensure the operating environment remains within the specified -40°C to +85°C range to maintain guaranteed performance parameters.

Voltage Reference Selection Notes

Select this component for space-constrained designs requiring a subminiature footprint. It is suitable for applications needing precise voltage referencing where power consumption must be minimized. Consider the 1.225V output level against system requirements. Verify compatibility with existing PCB footprints for the SC-70 package type.

Voltage Reference Part Context

This part belongs to the LM4050/LM4051 family of precision two-terminal shunt-mode bandgap voltage references. The series is designed for space-critical applications, offering multiple fixed voltage options in ultra-small packages. It serves as a drop-in replacement for larger SOT-23 versions when board space is limited.
