LT1790BIS6-3#TRPBF

Voltage Reference Overview

The LT1790BIS6-3#TRPBF is a micropower low dropout series voltage reference from Analog Devices, featuring a fixed 3V output. It utilizes curvature compensation and trimmed precision thin-film resistors to achieve high accuracy and low drift. The device operates within an industrial temperature range of –40°C to 85°C and offers B grade performance with ±0.1% initial accuracy and a maximum temperature coefficient of 25ppm/°C. It supports a wide supply voltage range up to 18V and includes current sinking capabilities.

Voltage Reference Feature Summary

• Combines high accuracy and low drift with low power dissipation and small package size
• Uses curvature compensation and post-package trimming for improved stability
• Capable of sourcing and sinking current for versatile circuit configurations

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging when sourcing. Confirm the 'I' designation matches the required –40°C to 85°C industrial temperature range for your application environment. Ensure compatibility with the 6-lead TSOT-23 footprint during PCB layout review.

Voltage Reference Selection Notes

Select this part for applications requiring a stable 3V reference in space-constrained designs. The B grade provides ±0.1% accuracy suitable for general precision needs. Consider the low supply current for battery longevity. Verify that the input voltage remains above the minimum dropout requirement for the expected load conditions.

Voltage Reference Part Context

This component belongs to the LT1790 family of micropower SOT-23 low dropout references. The family combines high accuracy with small package sizes. Variants are available in different grades (A, B) and temperature ranges (Commercial, Industrial). The LT1790 series is designed for battery-operated systems due to its low power and reduced dropout voltage characteristics.
