PJ1085
3 Amp Low Dropout Positive Voltage Regulator
He PJ1085 Series of high performance positive voltage
TO-220
TO-263
TO-252
TRegulators are designed for
use in applications
requiring
low dropout performance at full rated current, Additionally,
the PJ1085 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 PJ1085 Series are three terminal regulators with
fixed and adjustable voltage options available in popular
packages.
