LT6650CS5#TRPBF

Voltage Reference Overview

The LT6650CS5#TRPBF is a micropower, low voltage 400mV reference with an integrated rail-to-rail buffer amplifier in a 5-lead SOT-23 package. It operates from supply voltages ranging from 1.4V to 18V and draws only 5.6µA typical supply current. The device features postpackage trimming for improved accuracy, sourcing and sinking up to 200µA over temperature. Stability is ensured with any output capacitor of 1µF or higher.

Voltage Reference Feature Summary

• Micropower operation with 5.6µA typical supply current
• Integrated rail-to-rail buffer amplifier
• Postpackage trimmed for enhanced initial accuracy
• Capable of sourcing and sinking 200µA load current

Voltage Reference Applications

• Battery-operated systems
• Handheld instruments
• Industrial control systems
• Data acquisition systems
• Negative voltage references

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging and lead-free compliance. Confirm the CS5 grade corresponds to the specified commercial operating temperature range of 0°C to 70°C. Ensure the ordering part number matches the required package type and electrical specifications before procurement.

Voltage Reference Selection Notes

Select this component when a low voltage, adjustable reference is needed in a small footprint. It is suitable for applications requiring external scaling via feedback resistors. Consider the 0.75% maximum initial accuracy at 5V and the wide input voltage range when designing for varying supply conditions.

Voltage Reference Part Context

This part belongs to the LT6650 series of micropower voltage references. It is distinguished by its ability to operate at very low supply voltages down to 1.4V while maintaining stability. The series includes variants with different temperature grades and accuracy levels, all housed in the low-profile ThinSOT™ package.
