LTC1258CS8-2.5#TRPBF

Overview

The LTC1258CS8-2.5#TRPBF is a micropower bandgap voltage reference in an 8-lead SOIC package. It provides a fixed 2.5V output with a maximum initial accuracy of 0.15% and a temperature coefficient of 40ppm/°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 stably without an output bypass capacitor or with capacitance up to 1μF.

Feature Summary

• Micropower low dropout series reference utilizing curvature compensation for low temperature drift
• Capable of sourcing 10mA and sinking 2mA load currents
• Stable operation guaranteed with zero output bypass capacitor or capacitive loads up to 1μF

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 MSOP or SO package variant matches the design requirements. Check for lead-free finish compliance if required by assembly specifications. Ensure the component meets the specified 0°C to 70°C operating temperature range for the intended application environment.

Selection Notes

Select this part for applications requiring high precision with minimal power consumption. The low dropout characteristic allows operation from supply voltages close to the nominal output. Consider the small package size for space-constrained designs. Verify that the 10mA sourcing capability meets the peak load demands of the connected circuitry.
