Linear Technology has a 200mA two-terminal current source which is designed with a wide voltage range, high AC and DC impedance and has two floating terminals.

The LT3092 features 1% initial accuracy and a very low temperature coefficient. Output current is programmable from 0.5mA to 200mA and current regulation over 1.5V to 40V is better than 10ppm/volt.

Designed not to require an external capacitor, the LT3092 is suitable for "intrinsically safe" applications in which the output may be shorted and no sparking can be tolerated.

Reverse supply tolerance and thermal shutdown protect both the IC and the load.

The LT3092 is offered in three packages: the low profile (0.75mm) 8-lead DFN (3mm x 3mm), 8-pin SOT-23, and 3-pin power SOT-223 package.
