LM385MX-2.5/NOPB

Overview

The LM385MX-2.5/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, originally derived from the National Semiconductor portfolio. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±3%. The device operates within a temperature range of 0°C to 70°C and features a temperature coefficient of 150ppm/°C. Designed for surface-mount applications, it utilizes an 8-SOIC package. Electrical characteristics include a minimum cathode current of 20µA and a maximum operating current of 20mA.

Feature Summary

Fixed 2.5V output voltage reference
Micropower shunt regulation architecture
Surface-mount 8-SOIC packaging

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as legacy variants may differ. Ensure the specific suffix matches design requirements. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component when a stable 2.5V reference is required in space-constrained designs. The 8-SOIC package facilitates automated assembly. Evaluate thermal management needs against the specified operating temperature range. Compare performance metrics with adjustable variants if circuit flexibility is necessary.

Part Context

This part belongs to the LM385 family of micropower voltage references. The series includes adjustable versions and other fixed voltage options. Texas Instruments acquired National Semiconductor, integrating these products into their broader power management portfolio. The family is known for low power consumption and stability in precision analog circuits.

Replacement Considerations

LM385MX-2.5 is listed as obsolete. The LM385MX-2.5/NOPB serves as a direct replacement variant. Other compatible parts include LM385M/NOPB and LM385BYZ-2.5/NOPB depending on package requirements.
