DESCRIPTION

The SPX29501/02 are 5A highly accurate voltage regulators with a low dropout voltage of 420mV @ 5A. 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 include Enable, and Error Flag.
