LT6660JCDC-3#TRMPBF

Overview

The LT6660JCDC-3#TRMPBF is a micropower precision 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 ±0.4%. The device features a maximum temperature coefficient of 20ppm/°C and supports up to 20mA of output current. Operating specifications include a supply current range of 145µA to 220µA, an input voltage range of VOUT + 0.9V to 20V, and a specified operating temperature range of 0°C to 70°C.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging with lead-free compliance. Confirm the JCDC designation matches the required 3V output and ±0.4% accuracy grade. Ensure the 0°C to 70°C temperature range meets application thermal requirements before procurement.

Selection Notes

Select this component when a compact footprint is critical alongside moderate precision needs. The JCDC grade offers a balance between cost and performance compared to higher accuracy variants. Consider the 20mA sourcing capability for direct load driving without additional amplification stages.

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 stable performance across varying temperatures.
