DESCRIPTION
The SPX3940 is a 1A, accurate voltage regulators 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.
