LTC1258CMS8#PBF

Overview

The LTC1258CMS8#PBF is a micropower bandgap voltage reference in an 8-lead MSOP package. It provides a nominal output of 3V with a maximum initial accuracy of 0.2% and a temperature coefficient of 60 ppm/°C over the 0°C to 70°C range. The device features a maximum dropout voltage of 200mV at 10mA output current and draws only 4μA typical quiescent current. It can source up to 10mA and sink up to 2mA, operating from input voltages between VOUT + 0.2V and 12.6V.

Feature Summary

• Micropower low dropout series reference design utilizing curvature compensation for high accuracy
• Capable of sourcing 10mA and sinking 2mA without requiring an output bypass capacitor
• Internal P-channel pass transistor enables ultralow quiescent current operation

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and lead finish. Confirm that the component status matches project requirements, as datasheet information indicates this specific part number may be obsolete or superseded by tape and reel variants. Ensure compatibility with required operating temperature ranges before procurement.

Selection Notes

Select this component when a fixed 3V reference is required in a compact MSOP package. It is suitable for applications demanding low supply current and minimal dropout voltage. Consider the adjustable LTC1258 variant if custom voltage levels are needed. Verify that the specified accuracy and drift parameters meet the system precision requirements.

Part Context

This component belongs to the LTC1258 series of micropower low dropout references. The series includes fixed voltage options (2.5V, 3V, 4.1V, 5V) and an adjustable version. All variants share similar electrical characteristics regarding quiescent current and dropout performance, differing primarily in their factory-trimmed output voltage levels.

Replacement Considerations

The datasheet lists LTC1258CMS8#TRPBF as the tape and reel equivalent for the tube-packaged LTC1258CMS8#PBF.
