LM385M-2.5/NOPB

Overview

The LM385M-2.5/NOPB is a micropower shunt voltage reference from Texas Instruments, housed in an 8-SOIC package. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±3%. The device operates within a temperature range of 0°C to +70°C and features a temperature coefficient of 150 ppm/°C. Maximum shunt current is rated at 20 mA, while minimum operating current is 20 µA. Noise performance is specified at 120 µVrms over the 10 Hz to 10 kHz bandwidth.

Feature Summary

Provides stable micropower voltage reference functionality suitable for precision applications
Operates efficiently with low quiescent current requirements
Designed for surface-mount integration via standard SOIC packaging

Applications

Portable battery-powered instrumentation systems
Data acquisition circuits requiring stable reference sources
Microprocessor-based supervisory control logic

Procurement Notes

Verify the specific suffix configuration against official Texas Instruments documentation to ensure compatibility with RoHS standards and lead-free manufacturing processes. Confirm that the 8-SOIC package dimensions match your PCB footprint requirements precisely. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.5 V reference is required in space-constrained surface-mount designs. Ensure the application environment remains within the 0°C to +70°C operational temperature range. Verify that the load current does not exceed the maximum shunt rating of 20 mA. Consider the ±3% initial accuracy tolerance against system precision requirements during the design phase.

Part Context

This device belongs to the LM185/LM285/LM385 family of micropower voltage references. The 'M' suffix indicates the 8-SOIC surface-mount package variant. The '-2.5' designation specifies the fixed 2.5 V output voltage level. The '/NOPB' suffix denotes a non-plastic leaded (lead-free) package compliant with environmental directives.
