PJ1117
1 Amp Low Dropout Positive Voltage Regulator
T
he PJ1117 Series of high performance positive voltage
regulators are designed for use in applications requiring
low dropout performance at full rated current,
Additionally, the PJ1117 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. The PJ1117 Series are
three terminal regulators with fixed and adjustable voltage
options available in popular packages.
