6.0 AMP LOW DROPOUT POSITIVE VOLTAGE REGULATOR April 7, 1998 EZ1585D TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The EZ1585D is a high performance positive voltage regulator designed for use in applications requiring low dropout performance at full rated current. Additionally, the EZ1585D 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 EZ1585D has tight tolerance on reference voltage, ±1% at 25°C and ±1.5% over line, load and temperature, as well as a 6.0A maximum current. The EZ1585D is a three terminal regulator with adjustable output voltage available in the popular TO220 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 DEVICE EZ1585DCT PACKAGE TO-220 VOUT VOLTS 1.30 to 5.7 BLOCK DIAGRAM ABSOLUTE MAXIMUM RATINGS Parameter Input Supply Voltage Power Dissipation Thermal Resistance Junction to Case Control Power Symbol VIN PD Maximum 7 Internally Limited Units V W θJC θJA TJ TSTG TLEAD 0.7 3.0 50 0 to 125 -65 to 150 260 °C/W °C/W °C °C °C PIN CONFIGURATION Thermal Resistance Junction to Ambient Operating Junction Temperature Range Storage Temperature Range Lead Temperature (Soldering) 10 Sec Pentium Processor is a trademark of Intel Corp. 1 © 1998 SEMTECH CORP. 652 MITCHELL ROAD NEWBURY PARK CA 91320 6.0 AMP LOW DROPOUT POSITIVE VOLTAGE REGULATOR April 7, 1998 EZ1585D ELECTRICAL CHARACTERISTICS Unless otherwise specified, Adj IO = 10mA to 6.0A; 1.3V ≤=(VIN - VOUT) ≤=2.6V Test Conditions Parameter Reference Voltage (1) Test Limits TJ (5) Symbol VREF VIN Note 7 Note 8 IO 10mA≤IO≤5A 10mA≤IO≤6A 10mA≤IO≤5A Min 1.238 Typ Max 1.262 Units 10mA≤IO≤6A 25°C O.T. 1.250 1.231 1.269 V Adj Voltage Version (1) Note 7 Note 8 Line Regulation REG(LINE) REG(LOAD) VD Note 6 10mA 5V 25°C O.T. 25°C O.T. 0.015 0.035 0.05 0.2 1 1.1 0.2 0.2 0.3 0.4 % Adj Voltage Version Load Regulation (1) % Dropout Voltage (2) 25°C 5A 6A O.T.
