| 3.0 AMP LOW DROPOUT POSITIVE VOLTAGE REGULATORS November 22, 1999 EZ1587 TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The EZ1587 series of high performance positive voltage regulators are designed for use in applications requiring low dropout performance at full rated current. Additionally, the EZ1587 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 EZ1587 series are three terminal regulators with fixed and adjustable voltage options available in popular packages. FEATURES * Low dropout performance, * * * * * * * * 1.3V max. for EZ1587 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 Fixed/adjustable output voltage Line regulation typically 0.005% Load regulation typically 0.05% TO-220 or TO-263 packages ORDERING INFORMATION DEVICE EZ1587CT-X.X EZ1587CM-X.X PACKAGE TO-220 TO-263 (2) APPLICATIONS * Pentium(R) Processor supplies * PowerPCTM supplies * Other 1.3V to 5.7V microprocessor supplies * Low voltage logic supplies * Battery-powered circuitry * Post regulator for switching supply BLOCK DIAGRAM VOUT VOLTS See Note (1) See Note (1) Notes: (1) Where X.X denotes voltage options.
