LT6660
Tiny Micropower
Precision Series References
in 2mm 2mm DFN
FEATURES DESCRIPTIO
No Output Capacitor Required The LT 6660 is a family of micropower series references
Low Drift: 20ppm/C Max that combine high accuracy and low drift with low power
High Accuracy: 0.2% Max dissipation and extremely small package size. These se-
Low Supply Current ries references use curvature compensation to obtain
20mA Output Current Guaranteed low temperature coefcient, and laser trimmed precision
Reverse-Battery Protection thin-lm resistors to achieve high output accuracy. The
Low IR Reow Induced Stress: 0.02% Typ LT6660 will supply up to 20mA with excellent line regula-
Voltage Options: 2.5V, 3V, 3.3V, 5V and 10V tion characteristics, making it ideal for precision regulator
Space-Saving Alternative to the LT1460 applications.

The LT6660 family of series references provide supply
current and power dissipation advantages over shunt
U
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
Handheld Instruments
applications where PC board space is a premium, fast set-
