TS1083 7.5 Amp Low Dropout Positive Voltage Regulator Low dropout voltage 1.3V max. TO-220 General Description The TS1083 Series of high performance positive voltage regulators are designed for use in applications requiring low dropout performance at full rated current. Additionally, the TS1083 Series provide excellent regulation over variations due to changes in line, load and temperature. Outstanding features include low dropout performance at rated current, fast transient response, internal current limiting and thermal shutdown protection of the output device. The TS1083 Series are three terminal regulators with fixed and adjustable voltage options available in popular packages. Features a a a a Low dropout voltage 1.3V max. Full current rating over line and temperature Fast transient response Total output regulation 2% over line, load and temperature Block Diagram INPUT a a a a a Adjust pin current max 120A over temperature Line regulation typical 0.015%. Load regulation typical 0.05%.
