BCR401UW6
10 to 100mA LED CONSTANT CURRENT REGULATOR in SOT26 (SC74R) Description Features The BCR401U monolithically integrates a transistor, diodes and
resistors to function as a Constant Current Regulator (CCR) for LED
driving. The device regulates with a preset 10mA nominal that can be
adjusted with external resistor up to 100mA. It is designed for driving
LEDs in strings and will reduce current at increasing temperatures to
self-protect. Operating as a series linear CCR for LED string current
control, it can be used in applications with supply voltages up to 40V. п‚ With no need for additional external components, this CCR is fully
integrated into a SOT26 (SC74R) minimizing PCB area and
component count. п‚ п‚ п‚ п‚ п‚ LED Constant Current Regulator Using PNP Emitter-Follower with
