LT1790AIS6-3.3#TRPBF

Voltage Reference Overview

The LT1790AIS6-3.3#TRPBF is a micropower low dropout series voltage reference from Analog Devices, housed in a 6-lead plastic TSOT-23 package. It provides a fixed output voltage of 3.3V with an initial accuracy of ±0.05% and a maximum temperature coefficient of 10ppm/°C. The device operates within a supply voltage range of 3.8V to 18V and draws a maximum no-load supply current of 80µA. It supports both sourcing up to 5mA and sinking up to 3mA currents, ensuring stable performance across the industrial temperature range of –40°C to +85°C.

Voltage Reference Feature Summary

• Curvature compensation and trimmed thin-film resistors ensure high precision and low drift.
• Capable of sourcing and sinking current for versatile positive or negative reference configurations.
• Minimized thermally induced hysteresis through specialized post-package trimming processes.

Voltage Reference Applications

• Battery-operated equipment requiring low power dissipation
• Data acquisition systems needing precise analog references
• Industrial control systems utilizing compact surface-mount packaging

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the AIS6 designation corresponds to the industrial temperature grade and A-grade accuracy specifications required for your design. Ensure compatibility with standard SMD reflow profiles for the TSOT-23 package.

Voltage Reference Selection Notes

Select this component when high accuracy and low quiescent current are critical in space-constrained designs. The A-grade specification offers tighter tolerance than B-grade options. Consider the minimum input-output voltage differential requirements relative to your supply rail to ensure proper regulation under all load conditions.
