PRODUCT DESCRIPTION

The SPX1585 are low power 5A adjustable and fixed voltage regulators that are very easy to use. It requires only 2 external resistors

to set the output voltage for adjustable version. The SPX1585 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 microprocessor 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

applications. 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 IQ of this device flows into the load, which

increases efficiency.

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

regulator refer to the SPX1584 data sheet.
