LM385MX-1.2/NOPB

Overview

The LM385MX-1.2/NOPB is a micropower voltage reference diode manufactured by Texas Instruments, designed for surface-mount applications in an 8-SOIC package. It provides a fixed nominal output voltage of 1.235 V with an initial accuracy of ±2%. The device operates within a temperature range of 0°C to +70°C and features a maximum shunt current of 20 mA. Its low power consumption makes it suitable for battery-powered systems requiring stable voltage references.

Feature Summary

Provides a stable 1.235 V reference voltage with high precision
Designed for low-power operation in portable electronic devices
Surface-mount construction for automated assembly compatibility

Applications

Battery-powered measurement instruments
Portable data acquisition systems
Microprocessor supply monitoring circuits

Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as per the manufacturer's latest documentation. Confirm the 8-SOIC package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications before finalizing procurement.

Selection Notes

Select this component when a precise 1.235 V reference is required in a compact surface-mount form factor. Consider the ±2% initial accuracy and 150 ppm/°C temperature coefficient for circuit stability. Evaluate the 20 mA maximum shunt current against your load requirements to ensure adequate regulation margin.

Part Context

This part belongs to the LM385 family of micropower voltage reference diodes from Texas Instruments. It shares functional similarities with other variants like the LM385M-1.2 but includes the NOPB suffix indicating specific manufacturing attributes. The family is widely used in industrial and consumer electronics for providing reliable reference voltages.
