SPX1584

SPX1584 8A Low Dropout Voltage Regulator Adjustable & Fixed 3.3V FEATURES Adjustable Output Down to 1.2V or Fixed 3.3V Output Current of 8A Low Dropout Voltage Extremely Tight Load and Line Regulation Current & Thermal Limiting Standard 3-Terminal Low Cost TO-220 Similar to Industry Standard LT1083/LT1584 APPLICATIONS Powering Intel Pentium µP from +5V Supplies Power PCSupplies SMPS Post-Regulator High Efficiency “Green” Computer Systems High Efficiency Linear Power Supplies Portable Instrumentation Constant Current Regulators Adjustable Power Supplies Battery Charger PRODUCT DESCRIPTION The SPX1584 is a low power 8A Adjustable Voltage Regulator that is very easy to use. It requires only 2 external resistors to set the output voltage. This device is an excellent choice when using Powering Intel Microprocessor to convert from +5V to 3.3V supplies, and as a post regulator for switching supplies applications. The SPX1584 features low dropout of a maximum 1.5 volts. The SPX1584 offers full protection against over-current faults, reversed input polarity, reversed load insertion, over temperature operation, and positive and negative transient voltage. On-Chip trimming adjusts the reference voltage to 1%. The IQ of this device flows into the load, which increases efficiency. The SPX1584 is offered in a 3-pin TO-220 package compatible with older 3-terminal regulators. For a 5A low dropout regulator refer to the SPX1585 datasheet. PIN CONNECTIONS ...
