LM285BYM/NOPB

Overview

The LM285BYM/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, designed for precision applications requiring stable voltage regulation. It features an initial accuracy of 1% and operates within a temperature range of -40°C to +85°C. The device utilizes a SOIC-8 surface-mount package and supports a maximum shunt current of 20 mA with a minimum operating current of 10 µA. Its temperature coefficient is specified at 150 ppm/°C, ensuring reliable performance across varying thermal conditions in electronic circuits.

Feature Summary

• Provides precise voltage regulation with 1% initial accuracy
• Operates efficiently with micropower consumption characteristics
• Supports surface-mount installation via SOIC-8 packaging

Applications

• Precision measurement systems
• Portable instrumentation
• Battery-powered equipment

Procurement Notes

Verify the specific suffix 'BYM' against official Texas Instruments documentation to confirm the exact voltage output and tolerance grade, as variations exist within the LM285 family. Ensure the NOPB designation confirms lead-free compliance and RoHS status prior to integration into designs requiring environmental certification.

Selection Notes

Select this component when a compact surface-mount solution is required for low-power voltage referencing. Consider the 150 ppm/°C temperature coefficient and 1% initial accuracy limits against application requirements. Evaluate the SOIC-8 footprint constraints and the 20 mA maximum shunt current capability to ensure compatibility with the target circuit design.
