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.
The SPX3940 is offered in 3-pin SOT-223, TO-220 & TO-263 packages. For a 3A version, refer
to the SPX29300 data sheet.
