LT1009ILP

Voltage Reference Overview

The LT1009ILP is a precision 2.5V integrated reference circuit manufactured by Texas Instruments, housed in a TO-92 surface-mount package with three pins. It features an initial accuracy of ±0.2% and operates within a temperature range of -40°C to +85°C. The device functions as a shunt regulator with a maximum load regulation of 6 mV. Physical dimensions include a width of 3.43mm, height of 3.68mm, and length of 4.83mm.

Voltage Reference Feature Summary

• Provides a stable 2.5V reference voltage with high initial precision.
• Designed for surface-mount installation in compact applications.
• Operates reliably across extended industrial temperature ranges.

Voltage Reference Applications

• Precision analog signal conditioning circuits
• Data acquisition systems requiring stable voltage references
• Calibration equipment needing low-drift reference sources

Voltage Reference Procurement Notes

Verify the specific suffix ILP corresponds to the TO-92 surface-mount variant when ordering. Confirm that the required operating temperature range aligns with the -40°C to +85°C specification. Ensure the application circuit accommodates the shunt regulator topology and current requirements. Cross-reference datasheet revisions to confirm pinout consistency.

Voltage Reference Selection Notes

Select this component when a fixed 2.5V reference with ±0.2% tolerance is required in a small surface-mount form factor. Consider the shunt configuration for simple biasing needs. Evaluate thermal management if operating near the upper temperature limit. Compare against through-hole alternatives if board space permits different packaging constraints.

Voltage Reference Part Context

This part belongs to the LT1009 series of precision voltage references. The series includes various packages such as SOIC and DIP options. The ILP suffix specifically denotes the TO-92 surface-mount package variant. This family is designed for applications demanding high stability and low drift without external trimming.

Voltage Reference Replacement Considerations

The LM236 is listed as a similar product in the same series. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement supports the required surface-mount mounting style and temperature range.
