<\/span>Introduction<\/span><\/h2>\n\n\n\n

Many electronic systems require high-voltage DC power supplies for their operation, such as industrial control systems and test and measurement equipment. These applications requires high voltage DC supply that must provide a stable output. Modern SMPS are used for such cases, but not always preferred due to their high efficiency!<\/p>\n\n\n\n

In many cases, linear regulators are a suitable solution in high-voltage, low-current applications. In many practical cases, designers prioritize low output noise, predictable behavior, and circuit simplicity over efficiency. That is where TL783 voltage regulators come into play!<\/p>\n\n\n\n

Linear regulators continue to play an important role in such environments. Unlike switching converters, linear regulators do not introduce high-frequency switching noise or electromagnetic interference, making them particularly attractive for sensitive analog circuits and bias supplies.<\/p>\n\n\n\n

This technical guide focuses on the practical and safe use of the TL783 voltage regulator in high-voltage applications, with particular emphasis on designing a reliable 125 V linear power supply.<\/p>\n\n\n\n
