LM285MX-1.2

Overview

The LM285MX-1.2/NOPB is a micropower shunt voltage reference from the LM285 series, manufactured by Texas Instruments. It provides a fixed 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 temperature coefficient of 150 PPM/°C. It supports a maximum shunt current of 20 mA and a minimum operating current of 10 µA. The component is housed in an SOIC-8 surface-mount package.

Feature Summary

Provides a stable 1.235 V reference voltage suitable for precision applications
Operates with low quiescent current starting at 10 µA for power efficiency
Maintains performance across industrial temperature ranges from -40°C to +85°C

Applications

Portable battery-powered instrumentation
Data acquisition systems requiring precise voltage references
Microprocessor supervisory circuits

Procurement Notes

Verify the specific suffix (e.g., NOPB) to confirm lead-free compliance and packaging type. Ensure the SOIC-8 footprint matches the design layout. Confirm the 1% accuracy grade meets system requirements. Check for RoHS directive compliance documentation. Validate the operating temperature range against environmental conditions.

Selection Notes

Select this component when a low-cost, fixed 1.235 V reference is required. It is suitable for applications needing minimal standby current. Consider the 150 PPM/°C temperature coefficient for thermal stability needs. Compare with adjustable variants if variable output is needed. Evaluate package constraints for surface-mount assembly.

Part Context

This part belongs to the LM285 family of micropower shunt voltage references. It shares characteristics with other fixed-voltage variants like the LM285LP-2.5 but differs in output voltage and package type. The MX suffix indicates a tape-and-reel or cut-tape surface-mount option, distinct from through-hole TO-92 packages.
