Constant Current Regulator

& LED Driver

45 V, 20 mA

+ 15%, 460 mW Package

The linear constant current regulator (CCR) is a simple, economical

and robust device designed to provide a cost−effective solution for

regulating current in LEDs (similar to Constant Current Diode, CCD).

The CCR is based on Self-Biased Transistor (SBT) technology and

regulates current over a wide voltage range. It is designed with a

negative temperature coefficient to protect LEDs from thermal

runaway at extreme voltages and currents.

The CCR turns on immediately and is at 25% of regulation with

only 0.5 V Vak. It requires no external components allowing it to be

designed as a high or low−side regulator. The high anode-cathode

voltage rating withstands surges common in Automotive, Industrial

and Commercial Signage applications. The CCR comes in thermally

robust packages and is qualified to be UL94−V0 certified.
