high-voltage regulator

high-voltage regulator elektor october 1983 high-voltage regulator No, this article does not deal with a regulator for 10,000+ volts, but for all that, 125 V is "high" voltage when it concerns an integrated circuit. The type TL 783 IC does not only give an output of 125 V (maximum), but also allows a differential between its input and output voltages of 125 V. That is more than three times the usual 40 volts! An integrated, presettable voltage regulator with only three connections is not likely to hit the headlines these days. The news about the TL 783 is that it tolerates a voltage differential between its input and output of 125 V, and is capable of delivering an output of 125 V (maximum). On top of that, it equals or exceeds the parameters, with the exception of output current, of "improved" types like the LMX 17, LM 117, LM 217, and LM 317. The high voltage differential is made possible by the use of a DMOS (double-diffusion metal ox- ide semiconductor) output transistor. At t...
