CAT4101 Overview
The CAT4101 is a constant−current sink driving a string of high−brightness LEDs up to 1 A with very low dropout of 0.5 V at full load. It requires no inductor, provides a low noise operation and minimizes the number of ponents. The LED current is set by an external resistor connected to the RSET pin.
