LM385PW-2-5

Overview

The LM385PW-2.5 is a micropower shunt voltage reference manufactured by Texas Instruments, housed in an 8-pin TSSOP surface-mount package. 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 supports a maximum cathode current of 20 mA. Key electrical characteristics include a typical temperature coefficient of 20 ppm/°C and a noise level of 120 µVrms measured between 10 Hz and 10 kHz.

Feature Summary

• Provides stable fixed voltage reference for precision applications
• Designed for low power consumption via micropower architecture
• Compatible with standard surface-mount assembly processes

Applications

• Portable battery-powered instrumentation
• Data acquisition systems requiring stable reference voltages
• Microcontroller analog-to-digital converter references

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements prior to procurement. Ensure the selected variant matches the required package type and tolerance specifications for the intended design implementation.

Selection Notes

Select this component when a fixed 2.5V reference is required in a compact surface-mount form factor. Consider the ±3% initial accuracy and 20 ppm/°C temperature coefficient against application stability needs. Evaluate the 20 mA maximum current capability to ensure adequate load regulation for the target circuit design.
