PJ1086
1.5 Amp Low Dropout Positive Voltage Regulators
T
he PJ1086 seriesof high performance positive voltage
regulators designed for use in applications requiring low
dropout performance at full rated current, Additionally,
the PJ1086 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 PJ1086 Series
are three
terminal regulators with fixed and adjustable voltage
options available in popular packages.
