LM385M/NOPB

Overview

The LM385M/NOPB is an adjustable shunt voltage reference manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It operates within a temperature range of 0°C to +70°C and supports an output voltage span from 1.24 V to 5.3 V. The device features an initial accuracy of 2% and a temperature coefficient of 150 ppm/°C. Maximum shunt current capability is rated at 20 mA, with a minimum operating current of 20 µA.

Feature Summary

• Adjustable output voltage configuration via external resistors
• Low power consumption suitable for battery-operated systems
• Shunt regulation topology for stable reference generation

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered measurement devices
• Data acquisition systems needing stable reference sources

Procurement Notes

Verify the specific suffix and package type against official Texas Instruments documentation to ensure compatibility with design requirements. Confirm RoHS compliance status and manufacturing origin details through authorized distributors or direct manufacturer channels prior to procurement.

Selection Notes

Select this component when an adjustable shunt reference in an SOIC-8 package is required. Ensure the application voltage range falls between 1.24 V and 5.3 V. Consider the 150 ppm/°C temperature coefficient for thermal stability needs within the commercial temperature range.

Part Context

This part belongs to the LM385-ADJ series of micropower voltage references. It serves as a surface-mount alternative to through-hole variants like the LM385BYZ-2.5/NOPB, offering similar electrical characteristics in a compact form factor suitable for automated assembly processes.

Replacement Considerations

Direct pin-compatible replacements include other LM385M variants from Texas Instruments. Verify exact output voltage adjustability ranges and package dimensions before substituting with generic equivalents.
