PRODUCT DESCRIPTION
The SPX1085 are low power 3A 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 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 I
Q
of this device flows into load which
increases efficiency.
The SPX1085 are offered in a 3-pin TO-220, TO-263 & TO-252 packages compatible with other 3 terminal regulators. For a 8A low
dropout regulator refer to the SPX1085 data sheet.
