EZ1585B

5.0 AMP LOW DROPOUT POSITIVE VOLTAGE REGULATORS April 7, 1998 EZ1585B TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The EZ1585B is a high performance positive voltage regulator designed for use in applications requiring low dropout performance at full rated current. Additionally, the EZ1585B 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 EZ1585B has tight tolerance on reference voltage, ±1% at 25°C and ±1.5% over line, load and temperature. The EZ1585B is a three terminal regulator with adjustable output voltage available in the popular TO-220 package. FEATURES = Low dropout performance, 1.3V max. = Full current rating over line and temperature = Fast transient response = ±1.5% total output regulation over line, load and = = = = = temperature Adjust pin current max. 100µA over temperature Adjustable output voltage Line regulation typically 0.015% Load regulation typically 0.05% TO-220 package APPLICATIONS = Pentium® Processor supplies ORDERING INFORMATION BLOCK DIAGRAM DEVICE EZ1585BCT PACKAGE TO-220 VOUT VOLTS 1.30 to 5.7 ABSOLUTE MAXIMUM RATINGS Parameter Input Supply Voltage Power Dissipation Thermal Resistance Junction to Case Control Power Thermal Resistance Junction to Ambient Operating Junction Temperature Range Stor...
