CL520 - Fixed Constant-Current Linear LED Driver

General Description

The CL520 and CL525 are fixed-current linear regulators designed for driving LEDs at 20 mA and 25 mA, respectively.

With a maximum rating of 90V, these devices are able to withstand transients without the need for additional transient protection circuitry.

Key Features

  • 20 mA ±10% Constant-Current Driver for CL520.
  • 25 mA ±10% Constant-Current Driver for CL525.
  • 1V Dropout.
  • 4.75V to 90V Supply Range.
  • 90V Maximum Rating for Transient Immunity.
  • Temperature Compensated.
