LM385BZ/NOPB

Overview

The LM385BZ/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments. It provides a nominal output voltage of 1.235V with an initial accuracy of ±2.0%. The device operates within a temperature range of 0°C to +70°C and supports a maximum cathode current of 20mA. It utilizes a TO-92 three-pin package for through-hole mounting, featuring a compact physical footprint of 5.2 x 4.19 x 5.2mm.

Feature Summary

• Provides stable micropower voltage reference functionality in a standard through-hole package
• Operates as a shunt regulator topology suitable for low-power applications
• Maintains specified performance characteristics across commercial temperature ranges

Applications

• Portable instrumentation requiring stable reference voltages
• Battery-powered measurement systems
• General-purpose analog circuit biasing

Procurement Notes

Verify the specific suffix designation against official Texas Instruments documentation to confirm exact tolerance grades and RoHS compliance status. Ensure the procurement channel sources genuine components matching the LM385BZ/NOPB identifier to avoid counterfeit parts affecting precision requirements.

Selection Notes

Select this component when a fixed 1.235V reference is required in a through-hole configuration. Consider the ±2.0% initial accuracy and 150 ppm/°C temperature coefficient for budgeting system error margins. Evaluate thermal management needs relative to the 20mA maximum current capability in the TO-92 package.
