LM385BLPR-2-5

Overview

The LM385BLPR-2-5 is a micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed nominal output voltage of 2.5V with an initial accuracy tolerance of ±1%. The device operates within a cathode current range of 15 µA to 20 mA and features a temperature coefficient of 20 ppm/°C. It is housed in an 8-VSSOP surface-mount package and supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Provides stable micropower voltage regulation suitable for low-current applications
• Delivers high precision with tight initial accuracy tolerance
• Features low temperature drift for consistent performance across operating ranges

Applications

• Portable battery-powered instrumentation
• Data acquisition systems requiring precise reference voltages
• Handheld meters and test equipment

Procurement Notes

Verify the specific suffix 'BLPR' corresponds to the required ±1% accuracy grade, VSSOP-8 package, and tape-and-reel packaging format. Confirm that the 2.5V fixed output aligns with circuit design requirements before procurement.

Selection Notes

Select this component when a fixed 2.5V reference with higher precision than standard grades is needed. Ensure the application current stays within the 15 µA to 20 mA operational window to maintain specified accuracy and stability characteristics.

Part Context

This part belongs to the LM385 family of micropower shunt voltage references. It shares functional similarities with other variants like the LM385B-2.5 but differs in package type (VSSOP vs TO-92/DIP) and manufacturing lot specifications indicated by the suffix.

Replacement Considerations

LM385B-2.5 offers equivalent electrical performance in through-hole packages. LM385PWR-2-5 provides the same voltage and accuracy in a TSSOP package.
