CL2N3-G-P002

CL2 Simple 90V, 20mA, Temperature Compensated, Constant-Current LED Driver IC Features Description • • • • CL2 is a high voltage, temperature compensated, constant-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. 5.0 to 90V operating range (VA-B) 20 mA ±10% at 5.0 - 90V 0.01%/°C typical temperature coefficient Available in TO-243AA (SOT-89), TO-252(DPAK), & TO-92 packages • Can be paralleled for higher current 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 TO243AA (SOT-89), TO-252 (D-PAK), and TO-92 packages.
