PJ1082

10 Amp Low Dropout Positive Voltage Regulator

he PJ1082 Series of high performance positive voltage

T_{regulators are designed for applications requiring low}

TO-220

dropout

performance

at full rated

current,

Additionally, the PJ1082 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

PJ1082 Series are three terminal regulators with fixedand

adjustable voltage options available in popular packages.
