® SPX29300/01/02/03 Adjustable & Fixed Output, Fast Response Time 3A High Current, Low Dropout Voltage Regulator FEATURES ■ Adjustable Output Down To 1.25V ■ 1% Output Accuracy ■ Output Current of 3A ■ Low Dropout Voltage of 450mV @ 3A ■ Extremely Tight Load and Line Regulation ■ Extremely Fast Transient Response ■ Reverse-Battery Protection ■ Zero Current Shutdown (5 pin version) ■ Error Flag Signal Output for Out of Regulation State (5 pin version) ■ Standard TO-220 and TO-263 Packages SPX29300 3 Pin TO-263 1 2 3 VIN GND VOUT Now Available in Lead Free Packaging APPLICATIONS ■ Powering VGA & Sound Card ■ Power PC™ Supplies ■ SMPS Post Regulator ■ High Efficiency “Green” Computer Systems ■ High Efficiency Linear Power Supplies ■ Constant Current Regulators ■ Adjustable Power Supplies ■ Battery Charger DESCRIPTION The SPX29300/01/02/03 are 3A, highly accurate voltage regulators with a low drop out voltage of 450mV dropout (typical) @ 3A. These regulators are specifically designed for low voltage applications that require a low dropout voltage and a fast transient response. They are fully fault protected against over-current, reverse battery, and positive and negative voltage transients. On-Chip trimming adjusts the reference voltage to 1% initial accuracy. Other features in the 5 pin versions include Enable, and Error Flag. The SPX29300/01/02/03 are offered in 3 & 5-pin TO-220 & TO-263 packages. For a 1.5A version, refer to the SPX29150 data sheet.
