Overview
The LM285BXMX-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 nominal output voltage of 2.5 V with an initial accuracy of 1.5%. The device operates within a temperature range of -40°C to +85°C and features a maximum shunt current capability of 20 mA. It utilizes a SOIC-8 surface-mount package and exhibits a temperature coefficient of 150 ppm/°C. This component belongs to the LM285 series and is RoHS compliant.
Feature Summary
- Provides a fixed 2.5 V reference voltage suitable for precision analog circuits
- Operates as a micropower shunt regulator with low quiescent current requirements
- Maintains stability across industrial temperature ranges from -40°C to +85°C
Applications
- Precision data acquisition systems
- Portable battery-powered instrumentation
- Microprocessor supervisory circuits
Procurement Notes
Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific packaging configuration. Confirm that the SOIC-8 package variant matches your PCB footprint requirements. Cross-reference the manufacturer's datasheet for the latest thermal and electrical specifications before finalizing procurement decisions.
Selection Notes
Select this component when a fixed 2.5 V reference is required in a compact surface-mount form factor. Consider the 1.5% initial accuracy and 150 ppm/°C temperature coefficient against application tolerance needs. Ensure the circuit design accommodates the 20 mA maximum shunt current limit for proper regulation under varying load conditions.
Part Context
This device is part of the LM285 family of micropower voltage references, which includes adjustable and fixed voltage variants. The LM285 series is widely used in industrial and consumer electronics where space-constrained designs demand reliable voltage regulation. The BXMX suffix indicates a specific tape-and-reel packaging option within the SOIC-8 package family.
Replacement Considerations
LM285BYMX-2.5/NOPB offers higher 1% accuracy but shares the same package and voltage. LM285M/NOPB is an adjustable version in the same package family. Verify pin compatibility and thermal performance when substituting with other LM285 series variants.
