Linear, Fixed Constant Current LED Driver

The CL520 is a fixed, linear current regulator designed for driving LEDs at 20mA. With a maximum rating of 90V, it is able to withstand transients without the need for additional transient protection circuitry. It is ideally suited for applications employing single or multiple LEDs.The minimum dropo 20mA ±10% constant current drive\n1.0V dropout\n90V rating for transient immunity\nTemperature compensated\n4.75 - 90V supply range;
