LT1790ACS6-5#TRPBF

Voltage Reference Overview

The LT1790ACS6-5#TRPBF is a micropower low dropout series voltage reference from Analog Devices, featuring a fixed 5V output with ±0.05% initial accuracy and a maximum temperature coefficient of 10ppm/°C. It operates within a supply range of 5.5V to 18V, drawing a maximum supply current of 80µA. The device is housed in a 6-lead plastic TSOT-23 package and is specified for commercial temperatures from 0°C to 70°C.

Voltage Reference Feature Summary

• Curvature compensation and trimmed thin-film resistors ensure high output accuracy and low drift.
• Post-package trimming minimizes the temperature coefficient and enhances precision.
• Capable of sourcing and sinking current for versatile positive or negative reference applications.

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 matches the required tape and reel packaging format. Confirm that the lead-free finish designation aligns with environmental compliance requirements for the target assembly process. Ensure the commercial temperature grade specification meets the operational thermal constraints of the final design.

Voltage Reference Selection Notes

Select this component when a fixed 5V reference with high precision is required in a compact surface-mount footprint. The low supply current makes it suitable for battery-powered designs where power efficiency is critical. Verify that the input voltage remains within the specified dropout limits for both sourcing and sinking load conditions.

Voltage Reference Part Context

This part belongs to the LT1790 family of micropower SOT-23 low dropout references. The 'A' grade denotes the highest accuracy tier with ±0.05% tolerance. The 'S6' indicates the 6-lead TSOT-23 package, while '#TRPBF' specifies the tape and reel delivery with lead-free termination.
