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 5.0 - 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. Multiple CL2s 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.
