LTC1258CS8-3#TRPBF

Overview

The Analog Devices LTC1258CS8-3#TRPBF is a micropower bandgap voltage reference housed in an 8-lead plastic SO package. It provides a fixed output voltage of 3V with a maximum initial accuracy of 0.15% and a temperature coefficient of 40ppm/°C. The device features a typical quiescent current of 4μA and supports a maximum input voltage of 12.6V. It can source up to 10mA and sink up to 2mA, maintaining stability without an output bypass capacitor.

Feature Summary

• Combines high accuracy and low drift with very low supply current and small package size
• Features ultralow quiescent current and low dropout voltage ideal for battery-powered equipment
• Capable of sourcing 10mA and sinking 2mA for precision regulator applications
• Stable without an output bypass capacitor while supporting capacitance up to 1μF

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the MSOP or SO package variant matches your board layout requirements. Ensure the lead-free finish designation aligns with your assembly process standards. Cross-reference the manufacturer part number against official distributor catalogs to confirm availability status before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring a fixed 3V reference with minimal power consumption. The low dropout characteristic allows operation from supply voltages as low as VOUT plus 0.2V. Consider the 8-lead SO package for space-constrained designs where surface mount technology is preferred over through-hole alternatives.

Part Context

This part belongs to the LTC1258 series of micropower low dropout references manufactured by Analog Devices. The series includes various fixed voltage options and an adjustable version, all utilizing curvature compensation and trimmed thin-film resistors. These references offer power dissipation advantages over traditional shunt references by eliminating the need for idle load current.
