PRODUCT DESCRIPTION

The SPX1585 i s a low power 5A adjustable and fixed voltage regulator that i s very easy to use. It requires only 2 exte rnal resistors to set

the output voltage for the adjustable version. The SPX1585 devices are designed for low voltage applications that offe r lower dropout

voltage and faster transient response. This device is an excellent choice for use in powering low voltage microprocess or s that require a

lower dropout, faster transient response to regulate from +2.5V to 3.8V supplies , and as a post regulator for switching supplies applica-

tions. The SPX1585 features low dropout of a maximum 1.2 volts.

The SPX1585 offers full protection against over-current faults, reversed input polarity, reversed load insertion, and p ositive and negative

transient voltage. On-Chip trimming adjusts the reference voltage to 1%. The I

efficiency.

The SPX1585 devices are offered in a 3-pin TO-220 and TO-263 package compatible with other 3 terminal regulators. For a n 8A low

dropout regulator , refer to the SPX1584 data sheet.
