LT6660HCDC-10#TRMPBF

Overview

The LT6660HCDC-10#TRMPBF is a micropower series voltage reference from Analog Devices, providing a fixed 10V output. It features high accuracy with a maximum tolerance of 0.2% and low drift characterized by a temperature coefficient of 20 ppm/°C. The device operates within an input voltage range of VOUT + 0.9V to 20V, drawing a typical supply current of 270 µA at 25°C. It guarantees an output current capability of up to 20 mA and includes reverse-battery protection. Packaged in a compact 3-lead 2mm × 2mm DFN, it requires no output compensation capacitor.

Feature Summary

• Curvature compensation and laser-trimmed thin-film resistors ensure high precision and low temperature drift.
• Eliminates the need for an output compensation capacitor, saving board space and enabling fast settling times.
• Integrated reverse-battery protection prevents reverse current conduction.
• Low IR reflow induced stress minimizes output voltage shifts during surface mount assembly.

Applications

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

Procurement Notes

Verify the specific suffix #TRMPBF against official documentation to confirm tape and reel packaging specifications. Ensure the component meets RoHS compliance requirements as defined by the manufacturer's current standards. Confirm that the ordering information matches the exact part number to avoid discrepancies in package type or temperature grade.

Selection Notes

Select this part when a fixed 10V reference is required with minimal power consumption and high accuracy. The 0.2% initial tolerance and 20 ppm/°C drift make it suitable for applications demanding stable performance over temperature variations. Consider the 20mA output current capability for driving moderate loads without external buffering.

Part Context

This component belongs to the LT6660 family of tiny micropower precision series references. The family offers various voltage options including 2.5V, 3V, 3.3V, 5V, and 10V. The HC grade denotes the highest accuracy tier within the series, featuring tighter tolerances compared to JC and KC grades. All variants share the same compact 2mm x 2mm DFN footprint.

Replacement Considerations

LT1460 is cited as a space-saving alternative in datasheet documentation. Verify pin compatibility and electrical parameter alignment before substitution.

FAQ

Does the LT6660 require an output capacitor for stability?

No, the LT6660 does not require an output compensation capacitor, which allows for faster settling times and reduced PCB area usage.

What is the minimum input-to-output voltage differential?

The minimum dropout voltage is 0.9V at zero load current and increases to 1.4V at a 10mA load current.
