| CM1084 5.0 AMP POSITIVE VOLTAGE REGULATOR GENERAL DESCRIPTION The CM1084 series of high performance positive voltage dropout performance at full rated current. Additionally, the 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 CM1084 series are three terminal regulators with adjustable voltage options available in popular packages. FEATURES ! ! ! ! ! ! ! ! Low dropout performance 1.3V max. for CM1084 Full current rating over line and temperature Fast transient response 2% total output regulation over line, load and temperature Adjust pin current max 90A over temperature Adjustable output voltage Line regulation typically 0.015% Load regulation typically 0.1% TO-220, TO-252 and TO-263 packages regulators are designed for use in applications requiring low !
