LTC1258CMS8-4.1#TRPBF

Overview

The LTC1258CMS8-4.1#TRPBF is a micropower bandgap voltage reference in an 8-lead MSOP package, providing a nominal output of 4.096V. It features a maximum dropout voltage of 200mV at 10mA output current and a typical quiescent current of 4μA. The device offers a maximum initial accuracy of 0.18% and a temperature coefficient of 60ppm/°C over the 0°C to 70°C range. It can source up to 10mA and sink up to 2mA, with stability maintained without an output bypass capacitor.

Feature Summary

Micropower bandgap design with ultralow quiescent current for battery-powered applications
Low dropout voltage capability allowing operation near supply limits
Curvature compensation ensures low temperature drift and high precision
Stable without external output capacitors, saving board space

Applications

Battery-powered systems requiring extended life
Handheld instruments
Precision power supplies
A/D and D/A converter references

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the manufacturer designation matches Analog Devices Inc. or its predecessor Linear Technology Corporation. Ensure the part number corresponds to the 4.1V fixed output variant within the LTC1258 series. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a fixed 4.096V reference is needed with minimal power consumption. It is suitable for designs where input voltage may drop close to the output level due to the low dropout characteristic. Consider the 0.18% initial accuracy and 60ppm/°C drift specifications against system requirements. The MSOP package is ideal for space-constrained PCB layouts.

Part Context

This part 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 calibrated output voltage levels.
