LM285BXZ-1.2/NOPB

Overview

The LM285BXZ-1.2/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, designed for precision applications requiring stable voltage regulation. It features an output voltage of 1.235 V with an initial accuracy of 1% and a temperature coefficient of 150 ppm/°C. The device operates within a current range of 10 µA to 20 mA and supports surface-mount installation in an SOIC-8 package. It functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Provides a precise 1.235 V reference voltage with high initial accuracy
• Operates with micropower consumption suitable for battery-powered systems
• Features low dynamic impedance for stable performance under varying load conditions

Applications

• Portable instrumentation circuits
• Data acquisition systems
• Battery-operated measurement devices

Procurement Notes

Verify the specific suffix configuration against official Texas Instruments documentation to ensure compatibility with required packaging and environmental standards. Confirm that the SOIC-8 footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a fixed 1.235 V reference is required in a surface-mount format. Consider the 1% initial accuracy and 150 ppm/°C temperature coefficient against circuit tolerance requirements. Ensure the operating environment remains within the specified -40°C to +85°C range for optimal performance.

Part Context

This part belongs to the LM285 series of micropower voltage references from Texas Instruments. It shares architectural similarities with other LM285 variants but is distinguished by its fixed 1.235 V output and SOIC-8 surface-mount packaging, differentiating it from through-hole or adjustable versions within the same family.

Replacement Considerations

LM285BYMX-1.2/NOPB is a confirmed substitute offering identical electrical specifications and functionality.
