PJ1084
5 Amp Low Dropout Positive Voltage Regulator
THe PJ1084 Series are high performance positive voltage
regulators are designed for use in applications requiring
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 current
limiting and thermal shutdown protection of the output
device. The PJ1084 Series are three terminal regulators with
fixed and adjustable voltage options available in popular
packages.
