Overview
The LT6660JCDC-5#TRMPBF is a micropower precision series voltage reference providing a fixed 5V output. It features an initial accuracy of ±0.4% and a maximum temperature coefficient of 20ppm/°C over the 0°C to 70°C range. The device operates with an input voltage from VOUT + 0.9V to 20V, drawing a typical supply current of 200µA. It delivers up to 20mA of output current in a compact 3-lead 2mm × 2mm DFN package.
Feature Summary
- Curvature compensation and laser-trimmed resistors ensure high accuracy and low drift
- No external output compensation capacitor required for stability
- Reverse-battery protection prevents reverse current conduction
Applications
- Precision regulators
- A/D and D/A converters
- Sensor modules
Procurement Notes
Verify the specific suffix matches the required operating temperature range and accuracy grade. Confirm the package type and lead-free status align with assembly requirements. Check datasheet specifications for line regulation and load regulation limits relevant to the application load conditions.
Selection Notes
Select this part for applications requiring a fixed 5V reference with moderate accuracy needs. The JCDC variant offers a balance between cost and performance compared to higher precision HCDC options. Ensure the input voltage remains within the specified dropout and maximum limits for stable operation.
Part Context
This component belongs to the LT6660 family of tiny micropower precision series references. The family utilizes curvature compensation technology to achieve low temperature coefficients. It serves as a space-saving alternative to larger packages like the LT1460 while maintaining similar output current capabilities.
