XR46014

XR46014 High Voltage Constant Current Regulator Description 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.
