The XR46014 is an 80V constant current regulator that can drive upto 250mA. Users may adjust the regulating current from 10mA to 250mA through an external resistor.
A linear type over temperature protection function protects the system by decrease the current linearly when the junction temperature of the chip is higher than 125°C. Multiple XR46014 chips can be connected in parallel to provide higher driving current capability. The device is available in the SOT-223-3L package.
