DESCRIPTION

The SPX2941 is a 1A, accurate voltage regulator with a low drop out voltage of 280mV(typ.) 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 SPX2941 is offered in 5-pin

TO-220 & TO-263 packages. For a 3A version, refer to the SPX29300 data sheet.
