PRODUCT DESCRIPTION
The SPX1086 is a low power 1.5A 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 SPX1086 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 SPX1086 features low dropout of a maximum 1.2 volts.
The SPX1086 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 load which
increases efficiency.
The SPX1086 are offered in a 3-pin TO-220, TO-263 & TO-252 packages compatible with other 3 terminal regulators. For a 3A low
dropout regulator refer to the SPX1587 data sheet.
