SPX3940 1.0A 低漏失线性调节器（LDO)
The SPX3940 is a 1A, accurate voltage regulator with a low drop out voltage of 280mV(typ.) at1A. These regulators are specifically designed for low voltage applications that require a lowdropout 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 5-pinTO-220 & TO-263 packages. For a 3A version, refer to the SPX29300 data sheet.
