The SPX2941 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 overcurrent, reverse battery, and positive and negative voltage transients. The SPX2941 is offered in 5-pin TO-220 and TO-263 packages. For a 3A version, refer to the SPX29300 datasheet.
