It requires only 2 external resistors to set the output voltage for adjustable version. The SPX1085 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 SPX1085 features low dropout of a maximum of 1.5 volts. The SPX1085 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 load which increases efficiency. The SPX1085 are offered in a 3-pin TO-220, TO-263 & TO-252 packages patible with other 3 terminal regulators. For a 8A low dropout regulator refer to the SPX1085 data sheet.
