PRODUCT DESCRIPTION
The SPX1084 are low power 5A adjustable and fixed voltage regulators with 30V maximum V_IN. They are very easy to use. It
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
negative transient voltage. On-Chip trimming adjusts the reference voltage to 1%. The I_Q of this device flows into load, which
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.
