Application hints  
BCR401W serves as an easy to use constant current source for LEDs. In stand alone  
application an external resistor can be connected to adjust the current from 10 mA to 60 mA.  
Rext can be determined by using the diagram 'Output current versus external resistor',  
or by refering to diagram 'Output current versus reference voltage'. Look for your desired  
output current on the y axis and read out the corresponding Vdrop. Calculate Rext:  
Rext = Vdrop / (Iout -(Vdrop/Rint))  
Please take into account that the resulting output currents will be slightly lower due to the  
self heating of the component and the negative thermal coefficient.

AN077 gives hints to thermal design  
AN182 provides a guideline for replacing resistor biasing with BCR401W / BCR402W
