SPX1083 Datasheet | Sipex

FEATURES - Adjustable Output Down to 1.2V or Fixed 3.3V & 5V - 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” puter Systems - High Efficiency Linear Power Supplies - Portable Instrumentation - Constant Current Regulators - Adjustable Power Supplies - Battery Charger PRODUCT DESCRIPTION The SPX1083 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 SPX1083 features low dropout of a maximum 1.5 volts. The SPX1083 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 SPX1083 is offered in a 3-pin TO-220 package patible with older 3-terminal regulators. For a 5A low dropout regulator refer to the SPX1083 datasheet.
