EZ1083 Datasheet | SEMTECH

DESCRIPTION The EZ1083 series of high performance positive voltage regulators are designed for use in applications requiring low dropout performance at full rated current. Additionally, the EZ1083 series provides excellent regulation over variations 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 EZ1083 has both fixed and adjustable voltage options, while the EZ1083B is adjustable only for cost sensitive applications. These devices are available in the popular TO-220 package. Features - Low dropout performance, - - - - - - - - 1.3V max. for EZ1083, 1.45V max. for EZ1083B Full current rating over line and temperature Fast transient response ±2% total output regulation over line, load and temperature (±2.4% for EZ1083B) Adjust pin current max 90µA over temperature Fixed/adjustable output voltage (EZ1083) Line regulation typically 0.015% Load regulation typically 0.05% TO-220 package ORDERING INFORMATION DEVICE PACKAGE TO-220 VOUT VOLTS See Note (1) 1.30 to 5.7 APPLICATIONS - High current microprocessor supplies - Post regulators BLOCK DIAGRAM EZ1083CT-X.X EZ1083BCT Note: (1) Where X.X denotes voltage options.
