LT1790BCS6-5#TRMPBF

Voltage Reference Overview

The LT1790BCS6-5#TRMPBF is a micropower low dropout series voltage reference manufactured by Analog Devices Inc. It provides a fixed 5V output with B grade accuracy of ±0.1% and a maximum temperature coefficient of 25ppm/°C. The device operates within a supply voltage range of 3V to 18V, drawing a typical supply current of 60µA. It features a 6-lead TSOT-23 package and is specified for commercial operation from 0°C to 70°C.

Voltage Reference Feature Summary

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

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 #TRMPBF indicates tape and reel packaging with 500 units per reel as documented in official ordering information. Confirm the 'B' grade designation corresponds to the required ±0.1% initial accuracy and 25ppm/°C temperature coefficient specifications for your design constraints.

Voltage Reference Selection Notes

Select this component when a fixed 5V reference with micropower consumption is required in a small footprint. The B grade offers a balance of precision and cost compared to the A grade. Ensure the input voltage remains above the minimum dropout requirement for the intended load current.

Voltage Reference Part Context

This part belongs to the LT1790 family of micropower SOT-23 low dropout references. The family includes various output voltages and grades (A and B) with different temperature ranges (commercial and industrial). The CS6 suffix denotes the 6-lead TSOT-23 package suitable for surface mount assembly.
