GENERAL DESCRIPTION
The SPX29300/01/02 are 3A, highly accurate
voltage regulators with a low dropout
voltage of 600mV (typical) at 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 overcurrent, reverse battery, and positive and negative
voltage transients. On-Chip trimming adjusts the reference
voltage to 1% initial accuracy.
The SPX29300 is offered in a 3-pin TO-263 package, the SPX29301 is offered in a 5-pin TO-263 while SPX29302 is offered in a 5-pin TO-263 and 5-pin TO-220 packages.
