LM385M3X-2.5/NOPB

Overview

The LM385M3X-2.5/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, housed in an SOT-23 package. It provides a fixed output voltage of 2.5V 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, with a minimum operating current of 20 µA. Noise performance is specified at 120 µVrms over the 10 Hz to 10 kHz frequency band.

Feature Summary

Provides a stable 2.5V reference voltage suitable for precision applications
Operates with extremely low quiescent current for battery-powered systems
Compact surface-mount packaging facilitates space-constrained designs

Applications

Portable instrumentation requiring low power consumption
Battery-operated measurement devices
Data acquisition systems needing stable voltage references

Procurement Notes

Verify the specific suffix 'M3X' corresponds to the SOT-23-3 package configuration when sourcing. Confirm RoHS compliance status as indicated by the NOPB designation. Ensure the operating temperature range meets the application requirements, as this variant is rated for commercial temperatures only. Cross-reference datasheets for noise specifications if high-precision analog circuits are involved.

Selection Notes

Select this component when a fixed 2.5V reference is required in a small footprint. Compare against adjustable variants if circuit flexibility is needed. Consider the ±3% tolerance for budgeting accuracy margins. Evaluate thermal management needs despite the low power dissipation typical of shunt references.

Part Context

This part belongs to the LM385 family of micropower voltage references from Texas Instruments. It serves as a compact alternative to larger packages like SOIC or TO-92 while maintaining similar electrical characteristics. The series is designed for applications where power efficiency and size are critical constraints.
