Description
CL2 is a high voltage, temperature compensated, con-
stant-current source. The device is trimmed to provide
a constant current of 20 mA ±10% at an input voltage
of 5–90V. 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 20 mA. Multiple CL2s can also be
used in parallel to provide higher currents such as
40 mA, 60 mA or 80 mA. The device is available in TO-
243AA (SOT-89), TO-252 (D-PAK), and TO-92 pack-
ages.
