PRODUCT DESCRIPTION

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

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

voltage and faster transient response. This device is an excellent choice for use in powering low voltage microprocessors 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 positive and negative

transient voltage. On-Chip trimming adjusts the reference voltage to 1%. The I_Qof this device flows into the load, which increases

efficiency.

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

dropout regulator, refer to the SPX1584 data sheet.
