LT1009S8#TRPBF

Voltage Reference Overview

The LT1009S8#TRPBF is a precision shunt voltage reference from the LT1009 series, manufactured by Analog Devices Inc. It provides a fixed output voltage of 2.5V with an initial accuracy of 0.4% and a temperature coefficient of 25 PPM/°C. The device operates within a supply voltage range up to 35V and supports a maximum shunt current of 10mA. Designed for surface-mount applications, it is housed in an SOIC-8 package and functions reliably across an operating temperature range of 0°C to +70°C.

Voltage Reference Feature Summary

• Provides a stable 2.5V reference voltage suitable for high-precision analog circuits
• Features low temperature drift characteristics for consistent performance over varying thermal conditions
• Operates as a shunt regulator without requiring external shutdown control

Voltage Reference Applications

• Precision data acquisition systems
• Portable instrumentation
• Battery-powered measurement devices

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging distinct from tube variants. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure the ordering part number matches the required package style and quantity format for your manufacturing process.

Voltage Reference Selection Notes

Select this component when a fixed 2.5V reference is required in an SOIC-8 footprint. Consider the 0.4% initial accuracy and 25 PPM/°C temperature coefficient against application tolerance requirements. Evaluate the 10mA maximum shunt current capability to ensure adequate headroom for the reference circuit design.

Voltage Reference Part Context

This part belongs to the LT1009 family of micropower precision references. It shares core architectural similarities with other members like the LT1009S8#PBF but differs in packaging configuration. The TRPBF suffix indicates reel packaging optimized for automated surface-mount assembly lines.

Voltage Reference Replacement Considerations

LT1009S8#PBF serves as the tube-packaged equivalent within the same product line.
