DESCRIPTION  
The SPX29150/51/52/53 are 1.5A, highly accurate voltage regulators with a low dropout  
voltage of 390mV (typical) @ 1.5A. These regulators are specifically designed for low volt-  
age 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-pin and 5-pin TO-220 & TO-263 packages. For a 3A  
version, refer to the SPX29300 data sheet.
