EZ1086C & EZ1086I 1.5 Amp Positive Voltage Regulator POWER MANAGEMENT Description Features The EZ1086 series of high performance positive voltage Low dropout voltage: 1.3V max. for EZ1086C, regulators are designed for use in applications requiring 1.4V max. for EZ1086I low dropout performance at up to 1.5A. Additionally, the Full current rating over line and temperature EZ1086 series provides excellent regulation over Fast transient response variations in line, load and temperature. 2% total output regulation over line, load and temperature Outstanding features include low dropout performance Adjust pin current max 90A over temperature at rated current, fast transient response, internal Fixed/adjustable output voltage (EZ1086C) current limiting and thermal shutdown protection of the Line regulation typically 0.015% output device. Load regulation typically 0.05% Industrial temperature range (EZ1086I) A variety of options are available for maximum flexibility: the EZ1086C has both fixed and adjustable voltage TO-220 and TO-263 packages. Available in RoHS options and is designed for use in commercial applica- compliant package tions; the EZ1086I is adjustable only for industrial appli- Applications cations. Post regulators All devices are available in the popular TO-220 and Battery chargers TO-263 packages.
