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
