PRODUCT DESCRIPTION

The SPX2870 are low power 6.5A 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 SPX2870 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 SPX2870 features low dropout of a maximum 1.5 volts.

The SPX2870 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_Qof this device flows into the load, which

increases efficiency.

The SPX2870 are offered in a 3-pin TO-220 and TO-263 packages compatible with other 3 terminal regulators. For a 8A low dropout

regulator refer to the SPX2880 data sheet.
