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.
The SPX295001/02 are offered in 5-pin TO-220 & TO-263 packages. For a 1.5A version, refer
to the SPX29150 data sheet. For a 3A version, refer to the SPX29300 datasheet.
