LM385M3-2.5/NOPB

Overview

The LM385M3-2.5/NOPB is a micropower shunt voltage reference diode manufactured by Texas Instruments, designed for applications requiring stable voltage regulation with low power consumption. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±3%. The device operates within a temperature range of 0°C to +70°C and features a temperature coefficient of 150 ppm/°C. It is housed in a compact SOT-23 surface-mount package, suitable for space-constrained designs. The maximum shunt current rating is 20 mA, allowing it to handle moderate load variations while maintaining regulation.

Feature Summary

Provides a precise 2.5V fixed reference voltage with ±3% initial accuracy
Operates as a micropower shunt regulator for efficient energy usage
Engineered for stable performance across the commercial temperature range of 0°C to +70°C

Applications

Portable battery-powered instrumentation systems
Data acquisition and measurement circuits
Microcontroller analog-to-digital converter (ADC) reference inputs

Procurement Notes

Verify that the specific part number matches the required SOT-23 package and 2.5V fixed output specification. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the supplier source is authorized to guarantee component authenticity and traceability for quality assurance purposes.

Selection Notes

Select this component when a low-cost, fixed 2.5V reference is needed in a small SOT-23 footprint. It is appropriate for commercial-grade applications operating between 0°C and +70°C. Consider higher precision or wider temperature variants if stricter accuracy or industrial environmental conditions are required.

Part Context

This component belongs to the LM385 family of micropower voltage references from Texas Instruments. The 'M3' suffix indicates the SOT-23 surface-mount package variant, while '/NOPB' denotes lead-free construction and absence of specific packaging modifications. It serves as a direct replacement for older non-RoHS versions within the same electrical specification family.
