LT6660KCDC-3#TRMPBF

Voltage Reference Overview

The LT6660KCDC-3#TRMPBF is a micropower series voltage reference from Analog Devices, housed in a 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 of up to 20mA. Supply current ranges from 145µA to 220µA depending on conditions. It operates within an input voltage range of VOUT + 0.9V to 20V and supports specified temperatures from 0°C to 70°C.

Voltage Reference Feature Summary

• Curvature compensation combined with laser-trimmed thin-film resistors for 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 ensures minimal output voltage shift during assembly

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging when sourcing. Confirm the KCDC designation corresponds to the 0.5% accuracy grade and 50ppm/°C temperature coefficient specifications required for your design. Ensure the operating environment remains within the 0°C to 70°C specified temperature range for guaranteed performance parameters.

Voltage Reference Selection Notes

Select this component when a small footprint is critical but higher accuracy than shunt references is needed. The lack of required output capacitance makes it suitable for applications demanding fast settling times or intrinsic safety constraints where total capacitance must be minimized. Compare against the LT6660HCDC-3 if tighter accuracy (0.2%) or lower temperature coefficient (20ppm/°C) is required.

Voltage Reference 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 fixed voltage options including 2.5V, 3V, 3.3V, 5V, and 10V.

Voltage Reference Replacement Considerations

LT6660JCDC-3#TRPBF offers 0.4% accuracy and 20ppm/°C drift. LT6660HCDC-3#TRPBF provides 0.2% accuracy and 20ppm/°C drift. LT1460 is a larger package alternative with similar current capability.
