PRODUCT DESCRIPTION
The SPX2811 is a low power 10A adjustable and fixed voltage regulator that is very easy to use. It requires only two external
resistors to set the output voltage for the adjustable version. The SPX2811 is designed for low voltage applications that offer 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 SPX2811 features low dropout of a maximum 1.2 volts.
The SPX2811 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 SPX2811 is offered in a 3-Pin TO-220 and TO-263 package type, compatible with older 3 terminal regulators. For a 8A low
dropout regulator refer to the SPX1584 datasheet.
