PRODUCT DESCRIPTION
The SPX1585 is a low power 5A adjustable and fixed voltage regulator that is 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 ors 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 Q of this device flows into the load, w hich increases
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 SPX158 4 data sheet.
