LT6660JCDC-5#TRPBF

Overview

The LT6660JCDC-5#TRPBF is a micropower series voltage reference providing a fixed 5V output. It features a maximum accuracy of 0.4% and a temperature coefficient of 20ppm/°C over the 0°C to 70°C range. The device operates with an input voltage from VOUT + 0.9V to 20V, drawing a typical supply current of 180µA. It delivers up to 20mA of output current in a compact 3-lead DFN package.

Feature Summary

• Curvature compensation for low drift
• Reverse-battery protection
• No output capacitor required

Applications

• Precision regulators
• A/D and D/A converters
• Sensor modules

Procurement Notes

Verify the specific suffix #TRPBF indicates lead-free tape and reel packaging. Confirm the JCDC designation corresponds to the 0.4% accuracy grade and 20ppm/°C temperature coefficient specifications. Ensure the operating environment remains within the specified 0°C to 70°C range for guaranteed performance parameters.

Selection Notes

Select this component when space constraints require a small DFN package alongside moderate precision requirements. It serves as a space-saving alternative to larger packages like the LT1460. Consider the 20mA sourcing capability for applications needing higher drive currents than standard shunt references provide without external resistors.

Part Context

This part belongs to the LT6660 family of tiny micropower precision series references. The family utilizes laser-trimmed thin-film resistors for high accuracy. The JCDC variant specifically offers 0.4% initial accuracy, distinguishing it from the HC (0.2%) and KC (0.5%) grades within the same physical footprint.
