Tiny Micropower

Precision Series References

in 2mm × 2mm DFN

that combine high accuracy and low drift with low power

dissipation and extremely small package size. These se-

ries references use curvature compensation to obtain

low temperature coefficient, and laser trimmed precision

thin-film resistors to achieve high output accuracy. The

LT6660 will supply up to 20mA with excellent line regula-

tion characteristics, making it ideal for precision regulator

applications.

The LT6660 family of series references provide supply

current and power dissipation advantages over shunt

references that must idle the entire load current to oper-

ate. Additionally, the LT6660 does not require an output

compensation capacitor. This feature is important in

applications where PC board space is a premium, fast set-

tling is demanded, or total capacitance must be kept to a

minimum, as in intrinsic safety applications. Reverse-bat-

tery protection keeps these references from conducting

reverse current.
