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. 3-Lead 2mm 2mm 0.75mm DFN Package 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- APPLICATIO S 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- Precision Regulators tling is demanded, or total capacitance must be kept to a A/D and D/A Converters minimum, as in intrinsic safety applications.
