CL520

Doc.# DSFP-CL520

A052013

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.
