1 / 5 page 1 www.semtech.com EZ1083 7.5A Positive Voltage Regulator POWER MANAGEMENT Revision: December 21, 2005 The EZ1083 is a high performance positive voltage regulator designed for use in applications requiring low dropout performance at 7.5A. Additionally, the EZ1083 series provides excellent regulation over variations in line, load and temperature. Features include 1.4V dropout at 7.5 amps, fast transient response, internal current limiting and thermal shutdown protection of the output device. The EZ1083 has both fixed and adjustable voltage options. These devices are available in the popular TO-220 package. The EZ1083 is used in industrial systems to provide power to microprocessors and chipsets. It is also used to power ASICs in control systems for medical applications. Low dropout performance: 1.4V max. for EZ1083 Full current rating over line and temperature Fast transient response Adjust pin current max 90µA over temperature Fixed/adjustable output voltage (EZ1083) Line regulation typically 0.015% Load regulation typically 0.05% ±2% total output regulation over line, load and temperature TO-220 package. Available in WEEE and RoHS compliant package PC Motherboards Microcontroller systems Medical equipment Low power microprocessor systems Post regulation for switching power supplies Telecommunication systems Description Features Applications Fixed Voltage Regulator Adjustable Voltage Regulator Typical Application Circuit VIN > 4.75V VOUT = 3.45V VOUT = 3.3V VIN > 4.75V U1 EZ1083 1 2 3 ADJ OUT IN TAB + C2 10uF Tant.
