Application hints
BCR420U / BCR421U serve as an easy to use constant current sources for LEDs.
In stand alone application an external resistor can be connected to adjust the current from
10 mA to 150 mA. R
external resistor'. 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.
