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. On-Chip trimming adjusts the reference voltage to 1% initial accuracy. Other features in the 5 pin versions include Enable, and Error Flag. The SPX29300/01/02/03 are offered in 3 5-pin TO-220 TO-263 packages. For a 1.5A version, refer to the SPX29150 data sheet.
