LTC1258CMS8-3#TRPBF

Overview

The LTC1258CMS8-3#TRPBF is a micropower low dropout voltage reference from Analog Devices, housed in an 8-lead MSOP package. It provides a fixed 3V output 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 operates with a supply voltage up to 12.6V and draws a typical quiescent current of 4μA. It features a maximum dropout voltage of 200mV at 10mA output current and can source up to 10mA while sinking up to 2mA.

Feature Summary

• Micropower bandgap design utilizing curvature compensation for low drift
• Low dropout capability of 200mV maximum at full load
• Capable of sourcing 10mA and sinking 2mA without external components
• Stable operation with or without output bypass capacitors

Applications

• Battery-powered systems requiring extended life
• 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 manufacturer part number matches the required 3V output option within the LTC1258 series. Ensure the MSOP-8 package type aligns with PCB layout constraints. Cross-reference the datasheet revision to confirm electrical characteristics match the production batch requirements.

Selection Notes

Select this component for applications demanding low quiescent current and high accuracy in a small footprint. The 3V output is suitable for single-supply logic interfaces. Consider the 60 ppm/°C drift specification against environmental temperature variations. The internal P-channel pass transistor offers efficiency advantages over bipolar designs in dropout conditions.

Part Context

This part belongs to the LTC1258 series of micropower references, which includes options for 2.5V, 4.1V, 5V, and adjustable outputs. The series is characterized by its ultralow supply current and small MSOP or SO package availability. It serves as a precision reference element within power management integrated circuits (PMIC) subsystems.
