NSIJ: LED Driver, Adjustable Constant Current Regulator, 45 V, 20 mA. The adjustable 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. Adjustable Constant Current LASER Diode/LED driver. I was testing a couple of low-cost laser diodes that come from china and I was wondering why those diodes don’t have any protection/driver circuitry. Those diodes come with a simple series resistor for current control which is not a good idea nor stable. Laser diodes are harmful and should have some sort of constant current circuit as a basic Estimated Reading Time: 2 mins.  · Cheap laser diodes take approx. 30mA current. The driver can also be used to drive LEDs, operating voltage of this circuit is 5V DC, and maximum load mA. Project built using LT precision op-amp. The LT is a low power, high-speed rail-to-rail input, and output operational amplifier with excellent DC performance. The LT features reduced supply current, lower input Estimated Reading Time: 2 mins.

The LT is a low power, high-speed rail-to-rail input, and output operational amplifier with excellent DC performance. The LT features reduced supply current, lower input offset voltage, lower input bias current, and higher DC gain than other devices with comparable bandwidth.

The IC MBI is a high efficiency, step down DC to DC converter chip capable of driving high power LEDs at a safe 1 Amp constant current. The IC requires just. The TLDSJ is an integrated adjustable constant current source realized in a bipolar IC technology. The IC is designed to supply LEDs under the severe. Of course, you can always regulate down the voltage to a known level, then drive LEDs with a current limiting resistor but then, all LED.
