DESCRIPTION
The SPX29302A is a 3A, highly accurate voltage regulator with a low drop out voltage of
370mV (typical) @ 3A. These regulators are specifically designed for low voltage applications
that require a low dropout voltage and a fast transient response. Fault protection features
include over-current, reverse battery, and positive and negative voltage transients. On-Chip
trimming adjusts the reference voltage to 1% initial accuracy.
The SPX29302A is offered in 5-pin TO-220 & TO-263 packages.
