LM385BYZ/NOPB

Overview

The LM385BYZ/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments. It provides a nominal output voltage of 2.5 V with an initial accuracy of 3%. The device operates within a temperature range of 0°C to +70°C and features a maximum shunt current of 20 mA. It utilizes a TO-92-3 through-hole package and exhibits a temperature coefficient of 150 ppm/°C.

Feature Summary

• Micropower shunt voltage reference design
• Fixed 2.5 V nominal output voltage
• Through-hole TO-92-3 packaging

Applications

• Portable battery-powered instrumentation
• Data acquisition systems
• Microprocessor supply monitoring

Procurement Notes

Verify the specific suffix 'BYZ' against the official Texas Instruments datasheet to confirm pinout and tolerance specifications. Ensure the component meets RoHS compliance requirements for the intended application environment. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and sourcing channels.

Selection Notes

Select this component when a fixed 2.5 V reference is required in a through-hole configuration. Consider the 3% initial accuracy and 150 ppm/°C temperature coefficient for circuit precision requirements. Evaluate the 20 mA maximum shunt current capability against the load conditions to ensure stable operation within the specified commercial temperature range.

Part Context

This component belongs to the LM385 family of micropower voltage references from Texas Instruments. The family includes adjustable and fixed voltage variants designed for low-power applications. The BYZ designation indicates a specific fixed voltage option housed in a TO-92 package, distinct from surface-mount or adjustable versions within the same series.
