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.
