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 SPX2940 is offered in 3-pin TO-220 & TO-263 packages. For a 3A version, refer to the SPX29300 data sheet. TYPICAL APPLICATIONS CIRCUIT VIN 6.8µF + 1 SPX2940 2 3 + 10µF VOUT Figure 1. Fixed Output Linear Regulator.
