LT1009CLPM

Voltage Reference Overview

The LT1009CLPM is a precision shunt voltage reference manufactured by Texas Instruments, delivering a fixed output of 2.5 V. It features an initial accuracy of 0.2% and a temperature coefficient of 25 PPM/C. The device operates within a current range of 400 uA to 10 mA and supports through-hole mounting in a TO-92-3 package. It functions reliably across a temperature range of -40 C to +85 C.

Voltage Reference Feature Summary

• Provides a stable 2.5 V reference with high initial accuracy
• Features low temperature drift for consistent performance
• Includes a third terminal for system error calibration

Voltage Reference Applications

• Precision analog-to-digital converter references
• High-resolution digital-to-analog converter biasing
• Calibration of measurement systems

Voltage Reference Procurement Notes

Verify the specific suffix CLPM against official datasheets to confirm the package type and temperature grade. Ensure compatibility with existing circuit designs regarding thermal management and current limits. Confirm RoHS compliance status as required by project specifications before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a fixed 2.5 V reference with tight tolerance is required. The TO-92-3 package suits through-hole applications where space allows. Consider the operating current range to ensure proper regulation under varying load conditions. Verify that the 25 PPM/C drift meets the system's long-term stability requirements.

Voltage Reference Part Context

Part of the LT1009 series, which includes various packages like SOIC and TSSOP. This series offers precision trimming for minimal initial voltage tolerance and temperature drift. The LT1009 serves as a pin-to-pin replacement for older components like the LM136 in many designs.

Voltage Reference Replacement Considerations

LT1009CDRE4 is a documented substitute part number.
