Overview
The LM385MX/NOPB is an adjustable shunt voltage reference manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It provides a stable output voltage range from 1.24 V to 5.3 V with an initial accuracy of ±2%. The device features a temperature coefficient of 150 ppm/°C and supports a maximum shunt current of 20 mA. It operates within a commercial temperature range of 0°C to +70°C and belongs to the LM385-ADJ series.
Feature Summary
- Adjustable output voltage capability via external resistors
- Low power consumption suitable for battery-operated systems
- Shunt regulation topology for precise voltage control
Applications
- Portable instrumentation requiring stable reference voltages
- Battery-powered measurement devices
- General-purpose analog circuit references
Procurement Notes
Verify the specific suffix and package type against official Texas Instruments documentation to ensure compatibility with design requirements. Confirm RoHS compliance status and operating temperature range specifications prior to integration. Cross-reference datasheet parameters such as initial accuracy and temperature coefficient to validate suitability for the intended application environment.
Selection Notes
Select this component when an adjustable voltage reference in an SOIC-8 package is required for commercial temperature applications. Consider the 150 ppm/°C temperature coefficient and ±2% initial accuracy limits during circuit design. Ensure the load current remains within the specified 20 mA maximum shunt current limit for proper regulation.
Part Context
This part belongs to the LM385 family of micro-power shunt voltage references. It serves as an adjustable variant within the series, offering flexibility in setting reference levels compared to fixed-output counterparts. The LM385 series is widely used in general-purpose analog applications where low cost and moderate precision are sufficient.
Replacement Considerations
LM385M/NOPB is a verified tube-packaged equivalent in the same SOIC-8 package. LM285M/NOPB offers extended temperature range (-40°C to +85°C) but requires verification of pinout and electrical parameter compatibility.
