LT6660JCDC-3.3

Overview

The LT6660JCDC-3.3#TRPBF is a micropower series voltage reference providing a fixed 3.3V output with 0.4% initial accuracy and a maximum temperature coefficient of 20ppm/°C. It operates within an input voltage range of VOUT + 0.9V to 20V, drawing a typical supply current of 180µA at 25°C. The device guarantees a 20mA output current capability and features reverse-battery protection. Packaged in a compact 3-lead 2mm × 2mm DFN format, it eliminates the need for an external output compensation capacitor.

Feature Summary

Curvature compensation and laser-trimmed thin-film resistors ensure high precision and low drift
Eliminates the requirement for an output compensation capacitor to save board space
Reverse-battery protection prevents reverse current conduction

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates Lead Free Tape and Reel packaging when ordering. Confirm that the JCDC designation corresponds to the 0.4% accuracy grade and 20ppm/°C temperature coefficient specifications required for the design. Ensure the input voltage remains within the specified operational limits relative to the 3.3V output.

Selection Notes

Select this component for applications requiring a small footprint without output capacitors. The JCDC grade offers a balance between cost and performance, suitable for general precision needs. Consider the HCDC or KCDC variants if tighter tolerance or wider temperature ranges are necessary. Verify thermal management requirements as junction temperature affects hysteresis.

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 utilizes curvature compensation technology to achieve low temperature coefficients across various fixed voltage options including 2.5V, 3V, 3.3V, 5V, and 10V.
