LTC1258CS8#TRPBF

Overview

The LTC1258CS8#TRPBF is a micropower low dropout voltage reference in an 8-lead SOIC package. It provides a nominal output of 2.385V with a maximum initial accuracy of 0.4% and a temperature coefficient of 40ppm/°C. The device operates within a supply voltage range up to 12.6V, drawing a typical quiescent current of 6.5μA. 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 with curvature compensation for high accuracy and low drift
• Low dropout capability of 200mV maximum at full load current
• Capable of sourcing 10mA and sinking 2mA without requiring an output bypass capacitor

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 S8 package designation matches the required footprint. Ensure the component meets RoHS compliance standards for the intended manufacturing process. Check for any obsolescence notices or product change notifications from Analog Devices prior to finalizing procurement plans.

Selection Notes

Select this part for applications requiring a fixed low-voltage reference with minimal quiescent current consumption. The adjustable version allows for custom voltage setting via external resistors if standard values are insufficient. Consider the MSOP package option if board space constraints are more critical than thermal dissipation capabilities compared to the SOIC variant.

Part Context

This component belongs to the LTC1258 series of micropower references. It shares architectural similarities with other members like the LTC1258-2.5 and LTC1258-3 but offers a unique adjustable output voltage. The series utilizes thin-film resistors for trimming and an internal P-channel pass transistor to achieve superior efficiency over traditional shunt references.
