LM385BYZ-2.5/NOPB

Overview

The LM385BYZ-2.5/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, designed for commercial applications within a temperature range of 0°C to +70°C. It provides a fixed output voltage of 2.5 V with an initial accuracy of 3% and a temperature coefficient of 150 PPM/°C. The device operates with a minimum cathode current of 20 µA and a maximum of 20 mA. It is housed in a TO-92-3 through-hole package.

Feature Summary

Micropower operation suitable for battery-powered systems
Fixed 2.5 V output for precision referencing
Shunt regulation topology for stable voltage maintenance

Applications

Battery monitoring circuits
Portable instrumentation
Data acquisition systems

Procurement Notes

Verify the specific suffix NOPB indicates lead-free and RoHS compliance as per Texas Instruments standards. Confirm the TO-92-3 package type matches the target PCB footprint requirements. Ensure the commercial temperature grade (0°C to +70°C) aligns with the operational environment constraints of the final design application.

Selection Notes

Select this component when a fixed 2.5 V reference is required in a through-hole configuration. Compare against adjustable variants if circuit flexibility is needed. Consider the 150 PPM/°C temperature coefficient for thermal stability requirements. Evaluate the 20 mA maximum current limit against load demands to ensure proper shunt regulation without exceeding specifications.

Part Context

This part belongs to the LM385 series of micropower voltage references from Texas Instruments. The series includes various fixed voltage options and packages. The BYZ designation specifically identifies the 2.5 V fixed version in the TO-92 package format, distinguishing it from surface-mount or adjustable counterparts within the same family.

Replacement Considerations

LM385BYZ-2.5/NOPB is the direct equivalent of the non-NOPB version with updated environmental compliance. No other cross-references are confirmed in the provided documentation.
