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.
