DESCRIPTION
The SPX29300/01/02/03 are 3A, highly accurate voltage regulators with a low drop out
voltage of 450mV dropout (typical) @ 3A. 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.
