LT6660HCDC-3.3

Overview

The LT6660HCDC-3.3 is a micropower series voltage reference providing a fixed 3.3V output with 0.2% 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 and features reverse-battery protection. Packaged in a compact 3-lead 2mm × 2mm DFN, it eliminates the need for an output compensation capacitor.

Feature Summary

Curvature compensation and laser-trimmed thin-film resistors ensure high precision and low drift.
Reverse-battery protection prevents reverse current conduction.
Capacitor-free operation enables fast settling times and minimal board space usage.

Applications

Precision regulators
Handheld instruments
A/D and D/A converters

Procurement Notes

Verify the specific suffix against official documentation to confirm lead-free status and tape-and-reel packaging configuration. Confirm that the HC grade meets the required 0.2% accuracy and 20ppm/°C temperature coefficient specifications for the target application environment.

Selection Notes

Select this component when a small footprint and low quiescent current are critical alongside high accuracy. The HC grade offers the tightest tolerance within the family. Ensure the input voltage remains within the specified dropout limits to maintain regulation without requiring external output capacitors.

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 to achieve low temperature coefficients across various fixed voltage options.
