General Description
The Supertex CL2 is a high voltage, temperature
compensated, constant current source. The device is
trimmed to provide a constant current of 20mA±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 CL2 is to drive LEDs with
a constant current of 20mA. They can also be used
in parallel to provide higher currents such as 40mA,
60mA or 80mA. The device is available in SOT-89,
TO-252 (D-PAK), and TO-92 packages.
