SPX29300T-L-3-3

SPX29300/01/02 3A Low Dropout Voltage Regulator December 2016 Rev. 2.2.0 GENERAL DESCRIPTION The SPX29300/01/02 are 3A, highly accurate voltage regulators with a low dropout voltage of 600mV (typical) at 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 overcurrent, reverse battery, and positive and negative voltage transients. On-Chip trimming adjusts the reference voltage to 1% initial accuracy. The SPX29300 is offered in a 3-pin TO-263 package, the SPX29301 and SPX29302 are offered in a 5-pin TO-263 package. APPLICATIONS • Adjustable Power Supplies • Constant Current Regulators • Audio and Video/Graphic Cards • Battery Chargers FEATURES • 3A Guaranteed Output Current • Low Dropout Voltage of 600mV @ 3A • Adjustable Output down to 1.25V • 1% Output Accuracy • Tight Load and Line Regulation • Fast Transient Response • Reverse Battery Protection • Zero Current Shutdown (SPX29301/02) • Power Good Flag (SPX29301) • Lead Free 3-Pin TO-263 and 5-pin TO263 Packages TYPICAL APPLICATION DIAGRAM Fig. 1: SPX29300 and SPX29302 Application Diagrams Exar Corporation 48720 Kato Road, Fremont CA 94538, USA www.exar.com Tel. +1 510 668-7000 – Fax. +1 510 668-7001 SPX29300/01/02 3A Low Dropout Voltage Regulator ABSOLUTE MAXIMUM RATINGS OPERATING RATINGS These are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied.
