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.
