LM385BMX/NOPB

Overview

The LM385BMX/NOPB is an adjustable micropower shunt voltage reference manufactured by Texas Instruments. It operates within a supply voltage range of 1.24 V to 5.3 V and provides an initial accuracy of 2%. The device features a temperature coefficient of 150 ppm/°C and supports a maximum shunt current of 20 mA. Designed for surface-mount applications, it utilizes an SOIC-8 package and functions reliably across a commercial temperature range from 0°C to +70°C.

Feature Summary

Adjustable output voltage capability within the specified operational range
Micropower consumption characteristics suitable for battery-operated systems
Shunt regulation topology for stable voltage referencing

Applications

Battery-powered instrumentation circuits
Portable measurement devices requiring stable references
General-purpose analog signal conditioning

Procurement Notes

Verify that the ordering suffix /NOPB confirms RoHS compliance and absence of lead. Confirm the specific package variant matches the design requirements. Ensure the manufacturer designation aligns with Texas Instruments specifications. Cross-reference the component marking against official datasheets to prevent counterfeit substitution during acquisition.

Selection Notes

Select this component when an adjustable reference is required in an SOIC-8 footprint. The 2% initial accuracy and 150 ppm/°C temperature coefficient define its precision limits. Verify that the 20 mA maximum shunt current meets the circuit load requirements. Ensure the operating environment remains within the 0°C to +70°C commercial temperature range.

Part Context

This part belongs to the LM385 series of micropower voltage references. It serves as a surface-mount alternative to through-hole variants like the LM385BZ. The series offers both fixed and adjustable options for general-purpose voltage referencing applications in consumer and industrial electronics.
