LT6660HCDC-10#TRPBF

Overview

The LT6660HCDC-10#TRPBF is a micropower series voltage reference with a fixed 10V output, housed in a 3-lead 2mm × 2mm DFN package. It provides an initial accuracy of 0.2% and a maximum temperature coefficient of 20ppm/°C over the 0°C to 70°C specified range. The device guarantees a 20mA output current while maintaining low supply current characteristics. It operates within an input voltage range from VOUT + 0.9V up to 20V, featuring reverse-battery protection and requiring no output compensation capacitor.

Feature Summary

• Curvature compensation combined with laser-trimmed thin-film resistors ensures high precision and low drift.
• Eliminates the need for an output compensation capacitor, reducing board space requirements.
• Reverse-battery protection prevents reverse current conduction.
• Low IR reflow induced stress maintains stability during assembly.

Applications

• Precision regulators
• A/D and D/A converters
• Handheld instruments

Procurement Notes

Verify the specific suffix #TRPBF indicates lead-free tape and reel packaging. Confirm the HC grade corresponds to the 0.2% accuracy and 20ppm/°C temperature coefficient specifications. Ensure the operating environment remains within the 0°C to 70°C range for guaranteed performance parameters.

Selection Notes

Select this component when a compact form factor is required alongside high accuracy. The 10V output option suits applications needing higher reference levels without external scaling. Consider the 20mA sourcing capability for driving moderate loads directly. Verify that the input voltage headroom meets the minimum dropout requirement for the specific circuit design.

Part Context

This part belongs to the LT6660 family of tiny micropower precision series references. It serves as a space-saving alternative to larger packages like the LT1460. The family utilizes curvature compensation technology to achieve low temperature coefficients across various voltage options including 2.5V, 3V, 3.3V, 5V, and 10V.

Replacement Considerations

LT1460 is identified as a comparable larger-package alternative within the manufacturer's portfolio.
