PRODUCT DESCRIPTION

requires only 2 external resistors to set the output voltage for adjustable version. The SPX1084 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 SPX1084 features low dropout of a maximum of 1.2 volts.

The SPX1084 offers full protection against over-current faults, reversed input polarity, reversed load insertion, and positive and

increases efficiency.

The SPX1084 are offered in 3-pin TO-220 and TO-263 packages compatible with other 3 terminal regulators. For a similar 5A low

dropout voltage regulator refer to the SPX1084 datasheet. Also for higher current requirements, refer to the SPX1084 datasheet.
