General Description
The CL525 is a fixed, linear current regulator designed for
driving LEDs at 25mA. 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 accommodates extra
LEDs, permits lower supply voltages, and provides more
efficient operation.
The CL525 is offered in TO-252(D-PAK) and TO-92 packages.
