BCR42xUW6 Linear LED Constant Current Regulators

Diodes Inc. BCR42xUW6 Linear LED Constant Current Regulators integrate a transistor, diode and resistor to function as a Constant Current Regulator (CCR). The BCR42xUW6 regulate with a preset 10mA nominal that can be adjusted with an external resistor up to 350mA. It's designed for driving LEDs in strings and will reduce current at increasing temperatures to self-protect.
