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 5.0
- 90V. 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. Multiple CL2s can also be used in parallel to
provide higher currents such as 40mA, 60mA or 80mA. The
device is available in TO-243AA (SOT-89), TO-252 (D-PAK),
and TO-92 packages.
