LM385BYM-1.2/NOPB

Overview

The LM385BYM-1.2/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, designed for precision applications requiring stable voltage regulation. It provides a nominal output voltage of 1.235 V with an initial accuracy of 1%. The device operates within a temperature range of -40°C to +85°C and features a low temperature coefficient of 20 ppm/°C. It supports a maximum shunt current of 20 mA and requires a minimum operating current of 10 µA. The component is housed in an SOIC-8 surface-mount package.

Feature Summary

Provides a precise 1.235 V reference voltage with 1% initial accuracy
Features a low temperature coefficient of 20 ppm/°C for stability
Operates over an extended commercial temperature range of -40°C to +85°C
Designed for micropower applications with a wide operating current range

Applications

Portable instrumentation systems
Battery-powered measurement devices
Data acquisition systems
Microprocessor supply monitoring circuits

Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure compatibility with required tolerance and temperature specifications. Confirm that the SOIC-8 package dimensions align with the target PCB footprint. Check for RoHS compliance documentation as indicated by the NOPB designation. Ensure ordering quantities match the available reel or tube packaging options provided by authorized distributors.

Selection Notes

Select this component when a stable 1.235 V reference is needed in space-constrained designs. The SOIC-8 package facilitates automated surface-mount assembly processes. Consider the 20 ppm/°C temperature coefficient for environments with significant thermal fluctuations. Evaluate the 10 µA minimum current requirement to ensure proper regulation under light load conditions during system operation.

Part Context

This part belongs to the LM385 family of micropower voltage references from Texas Instruments. It serves as a surface-mount alternative to through-hole variants like the LM385BYZ series. The BYM suffix indicates the specific SOIC-8 package type and performance grade. It complements other fixed-voltage references in the portfolio for diverse packaging needs.
