LM385BYM-2.5/NOPB

Overview

The LM385BYM-2.5/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, designed for precision applications requiring stable voltage regulation. It provides a fixed output of 2.5 V with an initial accuracy of 1.5% and a temperature coefficient of 150 ppm/°C. The device operates within a junction temperature range of -40°C to +125°C and supports a maximum shunt current of 20 mA. Packaged in an 8-pin SOIC (D) surface-mount format, it ensures reliable performance across industrial environments while maintaining low power consumption characteristics typical of the LM385 series.

Feature Summary

Provides a precise 2.5 V reference voltage with 1.5% initial accuracy
Operates reliably across an extended industrial temperature range up to +125°C
Features micropower consumption suitable for battery-powered systems
Utilizes a compact 8-pin SOIC surface-mount package

Applications

Portable instrumentation requiring stable voltage references
Battery-operated measurement devices
Data acquisition systems needing accurate analog references
Industrial control circuits with strict thermal requirements

Procurement Notes

Verify the specific suffix 'BYM' indicates the correct temperature grade and package variant when sourcing. Confirm RoHS compliance status via the official datasheet as manufacturing processes may evolve. Ensure the ordering part number matches the required initial accuracy and temperature coefficient specifications for your design. Cross-reference with Texas Instruments documentation to validate availability and lead times through authorized distributors.

Selection Notes

Select this component when a fixed 2.5 V reference is needed with high accuracy in harsh thermal environments. The 1.5% tolerance offers better precision than standard LM385 variants. Consider the 8-pin SOIC package for automated surface-mount assembly. Evaluate power budget constraints as the micropower design suits low-drain applications. Compare against adjustable versions if variable reference voltages are required instead.

Part Context

This part belongs to the LM385 family of micropower shunt voltage references from Texas Instruments. The family includes adjustable and fixed voltage options in various packages. The LM385 series is widely used in general-purpose analog circuits where stability and low cost are prioritized. The 'NOPB' suffix denotes a lead-free, halogen-free product compliant with environmental standards.
