| PJ1082 10 Amp Low Dropout Positive Voltage Regulator T he PJ1082 Series of high performance positive voltage regulators are designed for applications requiring low dropout performance at full rated current, TO-220 Additionally, the PJ1082 Series provide 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 PJ1082 Series are three terminal regulators with fixedand adjustable voltage options available in popular packages. Pin: 1.Adj (com) 2.Out 3.In FEATURES * Low dropout voltage 1.3V max. Full current rating over line and temperature * * Fast transient response Total output regulation 2% over line, load and temperature * * * * * Adjust pin current max 120 A over temperature Line regulation typical 0.015%. Load regulation typical 0.05%. Fixed/adjustable output voltage TO-220 package ORDERING INFORMATION Device Operating Temperature (Ambient) PJ1082CZ PJ1082CZ-2.5 -20 to +85 TO-220 PJ1082CZ-3.3 NOTE: Contact factory for additional voltage option.
