CL520

Supertex inc. Linear, Fixed Constant Current LED Driver CL520 Features ►►20mA ±10% constant current drive ►►1.0V dropout ►►90V rating for transient immunity ►►Temperature compensated ►►4.75 - 90V supply range Applications ►► Specialty lighting ►► Low voltage signage General Description 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 dropout voltage of 1.0V accomodates extra LEDs, permits lower supply voltages, and provides more efficient operation. The CL520 is offered in TO-252(D-PAK) and TO-92 packages.
