Originally designed for telecommunication applications, it is also ideal for general purpose off-line uses due to its 450V input capability. The LR8 has an operating input voltage range of 12V to 450V, and features current limiting and thermal shutdown. Its output voltage is adjustable from 1.2V to 440V, by means of two external resistors. Its applications include industrial controls, motor controls, battery chargers as well as switchmode and linear power supplies. It is ideal for use in low power offline linear regulators, SMPS start-up circuits, and high voltage adjustable constant current sources that require operation from any rectified utility voltage worldwide.
