LT6660KCDC-2.5#TRPBF

Overview

The LT6660KCDC-2.5#TRPBF is a micropower series voltage reference from Analog Devices, housed in a compact 3-lead 2mm × 2mm × 0.75mm DFN package. It provides a fixed output of 2.5V with an initial accuracy of ±0.5% and a maximum temperature coefficient of 50ppm/°C over the 0°C to 70°C specified range. The device guarantees up to 20mA of output current while maintaining low supply current consumption. It features reverse-battery protection and does not require an output compensation capacitor.

Feature Summary

Curvature compensation combined with laser-trimmed thin-film resistors ensures high precision and low drift.
Reverse-battery protection prevents reverse current conduction.
Eliminates the need for an output compensation capacitor, saving board space and enabling fast settling times.

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 KCDC designation corresponds to the 0.5% accuracy grade and 50ppm/°C temperature coefficient. Ensure the operating environment remains within the 0°C to 70°C specified temperature range for guaranteed performance parameters.

Selection Notes

Select this component when a small footprint is critical but higher precision than shunt references is required. The KCDC variant offers a balance of cost and performance suitable for general-purpose precision applications. Consider the HCDC or JCDC variants if tighter accuracy (0.2% or 0.4%) or lower temperature coefficients are necessary for the 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 includes various voltage options (2.5V, 3V, 3.3V, 5V, 10V) and accuracy grades (HC, JC, KC) to suit different precision requirements within the same compact form factor.

FAQ

Does the LT6660KCDC-2.5 require an output capacitor?

No, the LT6660 family is designed to be stable without an output compensation capacitor, which helps minimize PCB space and allows for faster settling times.
