SPX29300

October 2010 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 is offered in a 5-pin TO-263 while SPX29302 is offered in a 5-pin TO-263 and 5-pin TO-220 packages.
