LTC1798CS8-3#TRPBF

Overview

The LTC1798CS8-3#TRPBF is a micropower bandgap voltage reference from the Analog Devices LTC1798 series, housed in an 8-lead plastic SO package. It provides a fixed nominal output voltage of 3V with a maximum initial accuracy of 0.15% and a maximum temperature coefficient of 40ppm/°C. The device operates within an input voltage range up to 12.6V and features a typical quiescent current of 4µA. It can source up to 10mA and sink up to 2mA, maintaining stability without an output bypass capacitor.

Feature Summary

• Micropower low dropout design utilizing curvature compensation for high accuracy
• Capable of sourcing 10mA and sinking 2mA load currents
• Stable operation guaranteed without external output capacitors

Applications

• Battery-powered systems
• Handheld instruments
• Precision power supplies
• A/D and D/A converters

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the component matches the exact manufacturer part number to ensure correct voltage output and package type. Check datasheet specifications for operating temperature ranges and electrical limits before integration.

Selection Notes

Select this component for applications requiring low supply current and minimal board space. The fixed 3V output eliminates the need for external resistor dividers found in adjustable versions. Ensure the input voltage remains above the minimum dropout threshold relative to the output voltage during operation.

Part Context

This part belongs to the LTC1798 series of micropower references, which includes options for 2.5V, 4.1V, and 5V outputs as well as an adjustable variant. All members share the same 8-lead SO package and core architecture, differing primarily in their factory-trimmed output voltage levels.

Replacement Considerations

LTC1798CS8-3#PBF serves as the tube-packaged equivalent of this component.
