TS1082
10 Amp Low Dropout Positive Voltage Regulator
Low dropout voltage 1.3V max.
TO-220
General Description
The TS1082 Series of high performance positive voltage regulators are designed for use in applications requiring low dropout
performance at full rated current. Additionally, the TS1082 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 TS1082 Series are three terminal regulators with fixed and
adjustable voltage options available in popular packages.
