LT6660KCDC-3

Overview

The LT6660KCDC-3 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 voltage of 3V with an initial accuracy tolerance of ±0.5%. The device features a maximum temperature coefficient of 50ppm/°C and guarantees an output current capability of up to 20mA. Supply current ranges from 145µA to 220µA depending on operating conditions. It operates within an input voltage range of VOUT + 0.9V to 20V and supports a specified temperature range of 0°C to 70°C.

Feature Summary

Curvature compensation combined with laser-trimmed thin-film resistors for high precision
Eliminates the need for an external output compensation capacitor
Reverse-battery protection prevents reverse current conduction
Low IR reflow induced stress ensures stability during assembly

Applications

Handheld Instruments
Precision Regulators
A/D and D/A Converters
Power Supplies
Hard Disk Drives
Sensor Modules

Procurement Notes

Verify the specific suffix 'KCDC' confirms the 3V output, ±0.5% accuracy, and 50ppm/°C temperature coefficient specifications. Ensure the '#TRMPBF' designation matches the required tape and reel packaging format and lead-free compliance status for your manufacturing process. Confirm availability as supply may be limited.

Selection Notes

Select this component when space constraints require a 2mm × 2mm footprint without sacrificing precision. The KCDC grade offers a balance of moderate accuracy (0.5%) and low drift (50ppm/°C) suitable for general-purpose applications. Consider the HCDC or JCDC grades if tighter tolerances are required, or verify that the 20mA sourcing capability meets the load requirements.

Part Context

This part belongs to the LT6660 family of tiny micropower precision series references. The family shares common architectural features including curvature compensation and low power dissipation. Variations exist across different output voltages (2.5V, 3V, 3.3V, 5V, 10V) and accuracy grades (HCDC, JCDC, KCDC), all utilizing the same small DFN package form factor.
