General Description
The Supertex CL1 is a high voltage, temperature
compensated, constant current source. The device is
trimmed to provide a constant current of 20mA±5%
at an input voltage of 45V. 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 CL1 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,
D-PAK and TO-92 packages.
