CL2
Simple 90V, 20mA, Temperature Compensated
Constant Current LED Driver IC
Features
General Description
TheSupertexCL2isahighvoltage,temperaturecompensated,
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.
► 5.0 to 90V operating range (VA-B)
► 20mA ±10% at 5.0 - 90V
► 0.01%/°C typical temperature coefficient
► Available in TO-243AA (SOT-89), TO-252 (D-PAK),
& TO-92 packages
► Can be paralleled for higher current
Atypical 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.
Applications
► LED driver
► Industrial lamp indicators
► Signage
► Accent lighting
► Automotive
► Constant current source
► Constant current sink

Product Marking
Absolute Maximum Ratings are those values beyond which damage to the
device may occur. Functional operation under these conditions is not implied.
Continuous operation of the device at the absolute rating level may affect device
reliability. All voltages are referenced to device ground.
