Overview
The LT6660KCDC-2.5#TRMPBF is a micropower series voltage reference from Analog Devices, housed in a 3-lead 2mm × 2mm × 0.75mm DFN package. It provides a fixed output of 2.5V with an initial accuracy tolerance of ±0.5% and a maximum temperature coefficient of 50ppm/°C. The device guarantees a sourcing output current up to 20mA and operates within an input voltage range of VOUT + 0.9V to 20V. Supply current for the 2.5V option ranges from 115µA to 175µA. It functions over a specified temperature range of 0°C to 70°C.
Feature Summary
- Curvature compensation combined with laser-trimmed thin-film resistors ensures high precision and low drift.
- Eliminates the need for an output compensation capacitor, reducing board space requirements.
- Reverse-battery protection prevents reverse current conduction.
- Low IR reflow induced stress minimizes output voltage shifts during soldering.
Applications
- Handheld Instruments
- Precision Regulators
- A/D and D/A Converters
- Power Supplies
Procurement Notes
Verify the specific suffix #TRMPBF indicates lead-free tape and reel packaging. Confirm the KCDC designation corresponds to the 0.5% accuracy grade and 50ppm/°C temperature coefficient specifications. Ensure the operating environment remains within the 0°C to 70°C specified range for guaranteed performance parameters.
Selection Notes
Select this component when a compact footprint is required alongside moderate precision needs. The 20mA output capability supports direct driving of loads without external buffering in many cases. Consider the 50ppm/°C drift specification against application thermal stability requirements compared to higher-grade HC or JC variants.
Part Context
This part belongs to the LT6660 family of tiny micropower precision series references. The family offers various output voltages including 2.5V, 3V, 3.3V, 5V, and 10V. Different letter grades (H, J, K) denote varying levels of initial accuracy and temperature coefficient performance within the same physical package.

FAQ
Does the LT6660KCDC-2.5 require an output capacitor?
No, the LT6660 family is designed to be stable without an output compensation capacitor, which helps minimize total capacitance and board space.
What is the minimum input-to-output voltage differential?
The minimum dropout voltage is 0.9V at zero load current, allowing operation with an input voltage as low as VOUT + 0.9V.
