PJ1082
10 Amp Low Dropout Positive Voltage Regulator
T
he PJ1082 Series of high performance positive voltage
regulators are designed for applications requiring low
dropout
performance
at full rated
current,
TO-220
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.
