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 tempareture 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.
