PJ1084
5 Amp Low Dropout Positive Voltage Regulator
T
He PJ1084 Series are high performance positive voltage
regulators are designed for use in applications requiring
TO-220
TO-263
low dropout performance at full rated current, Additionally,
the PJ1084 Series provides 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
limiting
and
current
thermal shutdown protection of the output
