General Description
The Supertex CL25 is a high voltage, temperature
compensated, constant current source. The device is trimmed
to provide a constant current of 25mA ± 10% at an input
voltage of 5-90V. No external components are required. The
device can be used as a two terminal constant current source
or constant current sink.
A typical application for the CL25 is to drive LEDs with a
constant current of 25mA. They can also be used in parallel
to provide higher currents such as 50mA, 75mA or 100mA.
The device is available in TO-92 and TO-243AA (SOT-89)
packaging.

Absolute Maximum Ratings are those values beyond which damage to the device may
occur. Functional operation under these conditions is not implied. Continuous operation
of the device at the absolute rating level may affect device reliability. All voltages are
referenced to device ground.
