Product details

3V fixed reference with ±0.5% initial accuracy

It accepts a wide input range from 5.5V to 30V, making it suitable for systems with unregulated or varying supply rails. Output current is rated at 20 mA, enough to bias multiple ADC inputs or a small sensor array without an external buffer. Noise performance is specified at 4 ppm p-p (0.1 Hz to 10 Hz) and 4 ppm rms (10 Hz to 10 kHz), a clean enough floor for 12- to 14-bit SAR converters. Housed in a 3-WFDFN with exposed pad (3-DFN, 2x2 mm), the part is a surface-mount fit for compact PCBs where board area is tight. The exposed pad helps thermal management when sourcing the full 20 mA at high input voltage.

This reduces supply-chain risk for both prototyping and volume manufacturing.

Package and mounting — 3-DFN with exposed pad

The LT6660KCDC-3#TRMPBF uses a 3-WFDFN exposed-pad package (supplier device package: 3-DFN, 2x2 mm). Mounting is surface-mount only. Cut tape (CT) is also available for smaller quantities.
