LT6654BIS6-1.25#TRMPBF

Voltage Reference Overview

The LT6654BIS6-1.25#TRMPBF is a precision series voltage reference with a fixed 1.25V output, housed in a 6-lead TSOT-23 package. It features B-grade initial accuracy of ±0.1% and a maximum temperature coefficient of 20ppm/°C. The device operates within a supply range of VOUT + 0.5V to 36V, drawing up to 600µA of supply current. It provides buffered output drive capable of sourcing and sinking ±10mA with low output impedance.

Voltage Reference Feature Summary

• Curvature compensation technology ensures high accuracy and low drift across the operating temperature range.
• Buffered output stage delivers stable regulation while sourcing or sinking significant load currents.
• Low noise performance minimizes measurement uncertainty in sensitive signal chains.
• Wide input voltage capability allows operation from standard supplies up to 36V.

Voltage Reference Applications

• High resolution data acquisition systems
• Industrial sensing and control circuits
• Precision regulators
• Medical equipment

Voltage Reference Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging containing 500 pieces. Confirm the B-grade designation matches the required ±0.1% accuracy and 20ppm/°C drift specifications for your design. Ensure the TSOT-23 footprint aligns with your PCB layout constraints.

Voltage Reference Selection Notes

Select this component when a compact solution is needed for applications requiring moderate precision (±0.1%) and wide supply voltage tolerance. The B-grade offers a balance between cost and performance compared to A-grade options. Verify that the 20ppm/°C drift meets thermal stability requirements for your specific environment.

Voltage Reference Part Context

This part belongs to the LT6654 family of small precision voltage references designed for portable and industrial use. The family includes various output voltages and grades (A, B, H, M) packaged in TSOT-23 or LS8 formats. The IS6 suffix denotes the I-grade temperature range (-40°C to 85°C) in the TSOT-23 package.
