LT6660HCDC-3#TRPBF

Overview

The LT6660HCDC-3#TRPBF is a micropower series voltage reference from Analog Devices, housed in a 3-lead 2mm × 2mm DFN package. It provides a fixed output voltage of 3V with an initial accuracy tolerance of ±0.2%. The device features a maximum temperature coefficient of 20ppm/°C and operates within a specified temperature range of 0°C to 70°C. Supply current is typically 180µA at 3V output, with a maximum of 220µA. It supports up to 20mA output current and requires an input voltage between VOUT + 0.9V and 20V.

Feature Summary

• Curvature compensation and laser-trimmed thin-film resistors ensure high precision and low drift.
• No output compensation capacitor is required, enabling fast settling times and minimal board space usage.
• Reverse-battery protection prevents reverse current conduction.
• Low IR reflow induced stress maintains stability during soldering processes.

Applications

• Handheld Instruments
• Precision Regulators
• A/D and D/A Converters
• Power Supplies

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 critical due to its 2mm × 2mm DFN footprint. Choose the HC variant for applications requiring the highest accuracy tier (0.2%) within the LT6660 family. Consider the 3V output option specifically for systems requiring this nominal rail without external adjustment.

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 while maintaining comparable output current capabilities. The family utilizes curvature compensation technology to achieve low temperature coefficients across various voltage options.

Replacement Considerations

LT6660JCDC-3#TRPBF offers 0.4% accuracy. LT6660KCDC-3#TRPBF offers 0.5% accuracy. Both share the same package and pinout but have different initial accuracy and temperature coefficient specifications.
