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 operati...
