LTC1258CMS8-2.5#TRPBF

Overview

The LTC1258CMS8-2.5#TRPBF is a micropower bandgap voltage reference providing a fixed 2.5V output in an 8-lead MSOP package. It features a maximum dropout voltage of 200mV at 10mA and a typical quiescent current of 4μA. The device offers 0.21% initial accuracy and a maximum 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 guaranteed without external output capacitors.

Feature Summary

• Curvature compensation for low temperature drift
• Internal P-channel pass transistor for low dropout
• Capacitor-free stability design
• Trimmed thin-film resistors for high accuracy

Applications

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

Procurement Notes
