LT1790BCS6-3#TRPBF

Voltage Reference Overview

The LT1790BCS6-3#TRPBF is a micropower low dropout series voltage reference from Analog Devices, housed in a 6-lead TSOT-23 package. It provides a fixed 3V output with an initial accuracy of ±0.1% and a maximum temperature coefficient of 25ppm/°C. The device operates within a supply voltage range of 3.5V to 18V and draws a maximum supply current of 80µA. Designed for commercial applications, it functions reliably between 0°C and 70°C.

Voltage Reference Feature Summary

• Curvature compensation combined with trimmed precision thin-film resistors ensures high output accuracy and low drift.
• Capable of both sourcing and sinking current, allowing operation as a micropower negative voltage reference.
• Post-package trimming minimizes the temperature coefficient and enhances overall output stability.

Voltage Reference Applications

• Handheld Instruments
• Negative Voltage References
• Industrial Control Systems
• Data Acquisition Systems
• Battery-Operated Equipment

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the B grade designation corresponds to the required 0.1% accuracy and 25ppm/°C temperature coefficient specifications. Ensure the commercial temperature range (0°C to 70°C) aligns with the target application environment requirements.

Voltage Reference Selection Notes

Select this component for designs requiring a compact SOT-23 footprint with stable micropower performance. The B grade offers a balance of cost and precision suitable for general-purpose references. Consider the 80µA supply current limit and 18V maximum input voltage when designing the power stage.
