LT1009CMS8#TRPBF

Voltage Reference Overview

The LT1009CMS8#TRPBF is a precision trimmed 2.5V shunt regulator diode manufactured by Analog Devices Inc. It features a maximum initial tolerance of ±5mV (0.2%) and operates within a temperature range of 0°C to 70°C. The device provides a guaranteed average temperature coefficient of 25 ppm/°C across the specified range. It utilizes an 8-lead plastic MSOP package and includes a third terminal allowing for a ±5% reference voltage adjustment to calibrate system errors.

Voltage Reference Feature Summary

• Precision on-chip trimming minimizes initial voltage tolerance and temperature drift
• Third terminal enables ±5% reference voltage adjustment for system error calibration
• Low dynamic impedance enhances versatility in various circuit applications

Voltage Reference Applications

• Reference for 5V Systems
• 8-Bit A/D and D/A Reference
• Digital Voltmeters
• Current Loop Measurement and Control Systems
• Power Supply Monitor

Voltage Reference Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging when sourcing from distributors. Confirm the CMS8 designation corresponds to the 8-lead MSOP package variant. Ensure the component meets the required 0°C to 70°C operating temperature range for your application environment before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a stable 2.5V reference with high initial accuracy is required. The availability of an adjustment terminal allows for fine-tuning without external complex networks. Consider the MSOP package size constraints and the specific thermal characteristics associated with the 8-lead plastic MSOP housing for your design.

Voltage Reference Part Context

This part belongs to the LT1009 series of precision shunt regulators. It serves as a direct pin-to-pin replacement for the LM136, offering improved performance without requiring external trim networks in many standard configurations. The series is designed for applications demanding low drift and high stability.
