DESCRIPTION
The SPX29150/51/52/53 are 1.5A, highly accuracy voltage regulators with a low drop out
voltage of 390mV dropout (typical) @ 1.5A. 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 in the 5 pin versions include Enable, and Error Flag.
The SPX29150/51/52/53 is offered in 3 & 5-pin TO-220 & TO-263 packages. For a 3A version,
refer to the SPX29300 data sheet.
