| PJ1085 3 Amp Low Dropout Positive Voltage Regulator T He PJ1085 Series of high performance positive voltage Regulators are designed for use in applications TO-220 TO-263 TO-252 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 limiting and current thermal shutdown protection of the output Pin: 1..Adj (Com) 2. Out 3. In device. The PJ1085 Series are three terminal regulators with fixed and adjustable voltage options available in popular packages.
