LM285BYMX-2.5

Overview

The LM285BYMX-2.5 is a micropower shunt voltage reference manufactured by Texas Instruments, designed for precision applications requiring stable voltage regulation. It operates within a temperature range of -40°C to +85°C and delivers a nominal output voltage of 2.5 V. The device features an initial accuracy of 1.5% and a maximum temperature coefficient of 150 ppm/°C. It supports a maximum shunt current of 20 mA and utilizes an SOIC-8 surface-mount package.

Feature Summary

Provides a stable 2.5 V reference voltage with high precision for sensitive circuitry
Operates efficiently at micropower levels suitable for battery-powered systems
Maintains performance across industrial temperature ranges from -40°C to +85°C

Applications

Portable instrumentation requiring low power consumption
Battery-operated measurement devices
Precision data acquisition systems

Procurement Notes

Verify the specific suffix 'BYMX' corresponds to the required accuracy grade and tape-and-reel packaging format. Confirm RoHS compliance status as indicated by the '/NOPB' designation in ordering information. Ensure the SOIC-8 footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.5 V reference is needed with moderate accuracy requirements. Consider the SOIC-8 package for automated surface-mount assembly processes. Evaluate the 150 ppm/°C temperature coefficient against system thermal stability needs to ensure adequate long-term precision without external compensation.

Part Context

This part belongs to the LM285 series of micropower shunt voltage references. It serves as a cost-effective alternative to Zener diodes, offering superior stability and lower noise characteristics. The series is widely used in general-purpose analog circuits where reliable voltage regulation is critical for signal integrity.
