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_Q of 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.
