No Preview Available ! February 2012 GENERAL DESCRIPTION The SPX3940 is a 1A, accurate voltage regulator with a low drop out voltage of 280mV (typical) at 1A. 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. The SPX3940 is offered in 3-pin SOT223 and TO-263 packages. For a 3A version, refer to the SPX29300 data sheet.
