Supertex inc. CL525 Linear, Fixed Constant Current LED Driver Features General Description 25mA 10% constant current drive The CL525 is a fixed, linear current regulator designed for driving LEDs at 25mA. With a maximum rating of 90V, it is able 1.0V dropout to withstand transients without the need for additional transient 90V rating for transient immunity protection circuitry. It is ideally suited for applications employing Temperature compensated single or multiple LEDs. 4.75 - 90V supply range The minimum dropout voltage of 1.0V accommodates extra Applications LEDs, permits lower supply voltages, and provides more efficient operation. Specialty lighting Low voltage signage The CL525 is offered in TO-252(D-PAK) and TO-92 packages. Typical Application Circuit V IN 4.75 90V 100nF 20mA VDD OUT 20mA Control GND CL525 Doc.
