Extremely Tight Load And Line Regulation Current & Thermal Limiting Standard 3-Terminal Low Cost TO-220, TO-263 & TO-252 Similar To Industry Standard LT1085/LT1585 APPLICATIONS Powering VGA & Sound Card Power PC Supplies SMPS Post-Regulator High Efficiency “Green” Computer Systems High Efficiency Linear Power Supplies Portable Instrumentation Constant Current Regulators Adjustable Power Supplies Battery charger PRODUCT DESCRIPTION The SPX1587 is a low power 3A adjustable and fixed voltage regulator that is very easy to use. It requires only 2 external resistors to set the output voltage for adjustable version. The SPX1587 are designed for low voltage applications that offers 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 SPX1587 features low dropout of a maximum 1.2 volts. The SPX1587 offers over current limit and full protection against reversed input polarity, reversed load insertion, and positive and negative transient voltage. On-Chip trimming adjusts the reference voltage to 1%. ...
