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 IQ of this device flows into the load which increases efficiency.
