LM385BM/NOPB

Overview

The LM385BM/NOPB is an adjustable 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 is housed in an SOIC-8 package. The component functions reliably across a commercial operating temperature range from 0°C to +70°C.

Feature Summary

Adjustable output voltage capability via external resistor network
Micro-power operation suitable for battery-powered systems
Shunt topology with low noise performance

Applications

Precision analog-to-digital converter (ADC) references
Portable instrumentation voltage regulation
Battery-operated measurement equipment

Procurement Notes

Verify the specific suffix 'M' indicates the SOIC-8 package variant when sourcing. Confirm the '/NOPB' designation ensures compliance with RoHS standards and absence of lead-based materials. Cross-reference the manufacturer part number against official Texas Instruments documentation to ensure authenticity and correct revision level before integration into production designs.

Selection Notes

Select this component when an adjustable reference voltage between 1.24 V and 5.3 V is required in a compact surface-mount form factor. The ±2% initial accuracy and 150 ppm/°C temperature coefficient make it suitable for general-purpose precision applications. Ensure the design accommodates the 20 mA maximum shunt current limit and operates within the specified 0°C to +70°C temperature range.

Part Context

This part belongs to the LM385 family of micropower voltage references. The LM385 series offers both fixed and adjustable versions in various packages including TO-92, SOIC, and SOT-23. The LM385BM/NOPB specifically represents the adjustable variant in the SOIC-8 package, providing flexibility in setting reference voltages while maintaining low power consumption characteristics typical of the series.
