LTC1258CS8-3#PBF

Overview

The LTC1258CS8-3#PBF is a micropower bandgap voltage reference providing a fixed 3V output in an 8-lead SOIC package. 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 0.15% and a maximum temperature coefficient of 40ppm/°C. It can source up to 10mA and sink up to 2mA, with stability maintained without an output bypass capacitor.

Feature Summary

• Combines high accuracy and low drift with very low supply current and small package size
• Ultralow quiescent current and low dropout voltage make it ideal for battery-powered equipment
• Stable without an output bypass capacitor while supporting capacitance up to 1μF

Applications

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

Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and RoHS compliance. Confirm the S8 package designation matches the required 8-lead plastic SO footprint. Ensure the operating temperature range meets the application's environmental specifications before procurement.

Selection Notes

Select this component when a fixed 3V precision reference is required with minimal power consumption. The low dropout characteristic allows operation from supply voltages close to the output level. Consider the 10mA sourcing capability for driving moderate loads directly without external buffering.

Part Context

This part belongs to the LTC1258 series of micropower low dropout references. The series includes options for 2.5V, 3V, 4.1V, and 5V outputs, as well as an adjustable version. These devices utilize curvature compensation and trimmed thin-film resistors to achieve their performance specifications.
