The SPX29150/51/52/53 are 1.5A, highly accurate voltage regulators with a low dropout voltage of 390mV (typical) at 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 overcurrent, 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 flags.
The SPX29150/51/52/53 is offered in 3-pin and 5-pin TO-220 and TO-263 packages. For a 3A version, refer to the SPX29300 datasheet.
