LM285BYM-2.5/NOPB

Overview

The LM285BYM-2.5/NOPB is a micropower shunt precision voltage reference manufactured by Texas Instruments, delivering a fixed output of 2.5 V. It operates within a temperature range of -40°C to +85°C and features an initial accuracy of 1.5%. The device supports a maximum shunt current of 20 mA with a typical temperature coefficient of 150 ppm/°C. Packaged in an SOIC-8 surface-mount format, it serves as a stable reference for low-power electronic systems requiring precise voltage regulation.

Feature Summary

Provides a fixed 2.5 V precision reference output suitable for high-accuracy applications
Operates efficiently at micropower levels with a maximum shunt current of 20 mA
Maintains stability across industrial temperatures from -40°C to +85°C

Applications

Analog-to-digital converter (ADC) reference sources
Digital-to-analog converter (DAC) voltage standards
Portable battery-powered instrumentation
Microprocessor supply monitoring circuits

Procurement Notes

Verify the specific suffix 'BYM' against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure the NOPB designation confirms lead-free compliance and RoHS status. Cross-reference the exact part number with the manufacturer's latest datasheet to validate electrical parameters and ordering information before procurement.

Selection Notes

Select this component when a fixed 2.5 V reference is required in a compact SOIC-8 package. It is appropriate for designs needing 1.5% initial accuracy and operation up to 85°C. Consider the 20 mA maximum current limit for biasing requirements. Compare against adjustable variants if programmable voltage is needed.

Part Context

This device belongs to the LM285 series of micropower shunt voltage references. It shares architectural similarities with other members like the LM285Z and LM285LP but differs in package style and specific performance tolerances. The series is designed for cost-effective, space-constrained applications requiring reliable voltage基准 without complex external circuitry.
