SPX3940 Datasheet PDF - Exar Corporation

GENERAL DESCRIPTION
The SPX 3940 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 respon se. They are fully fault protected against over - current, reverse battery, and positive and negative voltage transients.
