CL25

CL25 Simple 90V, 25mA, Temperature Compensated, Constant Current, LED Driver IC Features ► 5.0V to 90V operating range (VA-B) ► 25mA ±10% at 5-90V ► 0.01% / °C typical temperature coefficient ► No external components (two terminal device) ► Can be paralleled for higher current www.DataSheet4U.com General Description The Supertex CL25 is a high voltage, temperature compensated, constant current source. The device is trimmed to provide a constant current of 25mA ± 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. A typical application for the CL25 is to drive LEDs with a constant current of 25mA. They can also be used in parallel to provide higher currents such as 50mA, 75mA or 100mA. The device is available in TO-92 and TO-243AA (SOT-89) packaging.
