7.0 AMP LOW DROPOUT POSITIVE VOLTAGE REGULATORS November 22, 1999 TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The EZ1584 series of high performance positive voltage regulators are designed for use in applications requiring low dropout performance at full rated current. Additionally, the EZ1584 series provides excellent regulation over variations in line, load and temperature. FEATURES • Low dropout performance, • • • 1.3V max. for EZ1584 Full current rating over line and temperature Fast transient response ±2% total output regulation over line, load and temperature Adjust pin current max 90µA over temperature Fixed/adjustable output voltage Line regulation typically 0.015% Load regulation typically 0.05% TO-220 package Outstanding features include low dropout performance at rated current, fast transient response, internal current limiting and thermal shutdown protection of the output device. The EZ1584 series are three terminal regulators with fixed and adjustable voltage options available in the popular TO-220 package. • • • • • APPLICATIONS • Pentium® Processor supplies • PowerPC™ supplies • Other 2.5V to 3.6V microprocessor supplies • Low voltage logic supplies • Battery-powered circuitry • Post regulator for switching supply ORDERING INFORMATION BLOCK DIAGRAM EZ1584 DEVICE EZ1584CT-X.X PACKAGE VOUT VOLTS TO-220 See Note (1) Note: (1) Where X.X denotes voltage options.
