Constant Current Regulator
& LED Driver
45 V, 30 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 AEC-Q101 standard, and
UL94−V0 certified.

NOTE: Lead measurements are made by non−contact methods such as IR with treated surface to increase emissivity to 0.9.
Lead temperature measurement by attaching a T/C may yield values as high as 30% higher °C/W values based upon empirical
measurements and method of attachment.
