LT1790AIS6-3#TRMPBF

Voltage Reference Overview

The LT1790AIS6-3#TRMPBF is a micropower low dropout series voltage reference from Analog Devices, housed in a 6-lead plastic TSOT-23 package. It provides a fixed 3V output with an initial accuracy of ±0.05% and a temperature coefficient of 10ppm/°C. The device operates within a supply voltage range of 3.5V to 18V and draws a maximum supply current of 80µA. It supports both sourcing and sinking currents, ensuring stable performance across the industrial temperature range of –40°C to +85°C.

Voltage Reference Feature Summary

• Combines high accuracy and low drift with low power dissipation and small package size
• Uses curvature compensation and trimmed precision thin-film resistors for stability
• Capable of operating as a micropower negative voltage reference by sinking current

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm that the specific suffix #TRMPBF corresponds to the intended tape and reel packaging configuration. Ensure compliance with RoHS standards and check for any regional supply restrictions or limited availability status prior to finalizing procurement orders.

Voltage Reference Selection Notes

Select this part when precise 3V reference is required in space-constrained designs. The A-grade specification ensures tight tolerance and low drift suitable for high-performance applications. Consider the low dropout voltage and micropower consumption benefits over shunt references for battery-operated systems requiring efficient power management.

Voltage Reference Part Context

This component belongs to the LT1790 family of micropower SOT-23 low dropout references. The family utilizes curvature compensation technology to achieve low temperature coefficients. The AIS6-3 variant specifically denotes the industrial temperature grade, 3V output, and TSOT-23-6 package form factor within the broader Linear Technology portfolio.
